Frischwasser – Hygiëne-combiketel FKS: Legionellaveilige drinkwaterverwarming

Productoverzicht

De Frischwasser-combiketel FKS biedt legionellaveilige drinkwaterverwarming via een geïntegreerd roestvrijstalen golfbuis en combineert de voordelen van een boiler en een doorstroomverwarmer. Hij is geschikt voor gebruik met verschillende warmteopwekkers zoals zonne-energie, olie-/gasketels, hout- of pelletkachels en warmtepompen, en maakt tegelijkertijd de levering aan verwarmingscircuits mogelijk.

Functie en hygiëneconcept

De in de ketel gewikkelde roestvrijstalen golfbuis verwarmt drinkwater altijd vers en vermindert de voorraadvorming van sanitair warm water, waardoor het risico op legionellavorming wordt geminimaliseerd. Het grote oppervlak van de roestvrijstalen warmtewisselaar zorgt voor een hoog warmwatervermogen, een opofferingsanode is niet nodig en maakt de ketel onderhoudsvrij.

Materialen en verwerking

De tank bestaat uit hoogwaardig kwaliteitsstaal S235JRG2 volgens DIN 4753 / EN 12897, de drinkwater-warmtewisselaar uit roestvrijstalen golfbuis 1.4404 (Made in Germany). De ketel is intern ruw en extern geprimerd uitgevoerd, aansluitingen van de drinkwater-warmtewisselaar zijn zijdelings geplaatst.

Technische gegevens

Bedrijfsdruk van de tank tot max. 5 bar, bedrijfsdruk van de drinkwater-warmtewisselaar tot max. 10 bar. Volumevarianten variëren van 200 tot 2000 liter; modellen 200–400 L zijn voorzien van een moef voor een elektrische verwarmingspatroon, 600–2000 L hebben twee moeven. Een elektrische verwarmingsstaaf kan achteraf probleemloos worden gemonteerd.

Aansluitingen en integratie

Alle aansluitingen zijn zo ontworpen dat aangesloten energiebronnen en verbruikers onafhankelijk van elkaar kunnen worden bediend, waardoor de regelingsinspanning beperkt blijft. Bovendien is voor de warmwaterbereiding geen aparte regeling of pomp nodig, wat de installatie vereenvoudigt.

Warmtewisselaar en vermogen

De roestvrijstalen golfbuisslang als Frischwasser-warmtewisselaar biedt dankzij zijn grote oppervlak hoge doorstroom- en opbrengstwaarden. Een extra grote gladbuiswarmtewisselaar in de tank staat beschikbaar voor zonne- en verwarmingsaansluiting en zorgt voor efficiënte warmte-uitwisseling tussen verwarmings- en drinkwatercircuit.

Isolatievarianten

Beschikbaar zijn meerdere isolatievarianten: 100 mm EPS (efficiëntieklasse C), 130 mm EPS AirPor® (efficiëntieklasse B) en 150 mm PU-superhardschuim (efficiëntieklasse A) bij 600–1000 liter. Alle varianten hebben een zilvergrijs kunststofomhulsel met sluitlat; de PU-isolatie is uitgevoerd als afneembare omhulling.

EPS AirPor® polystyreen schuim – eigenschappen

De EPS AirPor® isolatie combineert EPS met grafietadditieven voor verbeterde warmtereflectie, lagere warmteverliezen en daardoor lagere energiekosten. Hij kenmerkt zich door perfecte pasvorm, eenvoudige montage, 100% recyclebaarheid en extra bodem- en dekselisolatie; warmtegeleidingsvermogen volgens DIN EN 12667: 0,0316 W/mK.

PU-superhardschuim-isolatie

De 150 mm PU-superhardschuim-isolatie biedt zeer goede isolatie-eigenschappen (warmtegeleidingsvermogen 0,023 W/mK), een vliescoating ter voorkoming van convectie en een robuuste, afneembare schaal met PS-omhulsel RAL 9006. Deze variant bereikt energie-efficiëntieklasse A en is eveneens recyclebaar.

Voordelen en bedrijfskosten

De combinatie van efficiënte warmte-isolatie, hoogwaardige roestvrijstalen warmtewisselaar en lage waterbevoorrading vermindert warmteverliezen en bedrijfsinspanning. EPS AirPor® kan tot 30 % minder verliezen opleveren in vergelijking met conventionele isolaties, wat zich vertaalt in lagere energiekosten en betere langetermijnprestaties.

Installatie, onderhoud en veiligheid

De installatie is eenvoudig: aansluitingen zijn vanzelfsprekend geplaatst, een pomp of regeling voor de warmwaterbereiding is niet nodig, en elektrische verwarmingsstaven kunnen achteraf worden ingebouwd. Door het weglaten van opofferingsanodes vervalt routinematige anodevervanging; de ketel is daardoor nagenoeg onderhoudsvrij.

Toepassingsgebieden

De FKS is universeel inzetbaar in een- en meergezinswoningen, commerciële objecten en toepassingen met gecombineerde warmtebronnen, met name daar waar hygiënische drinkwaterbereiding en flexibele systeemintegratie gewenst zijn. Hij is bijzonder geschikt voor installaties met zonne-ondersteuning en meerdere warmteopwekkers.

Samenvatting

De Frischwasser-hygiëne-combiketel FKS verenigt hygiënische Frischwassertechniek, flexibele aansluitmogelijkheden en efficiënte isolatievarianten in een onderhoudsarm systeem. Robuuste materialen, eenvoudige montage en hoge energie-efficiëntie maken hem tot een praktijkgerichte oplossing voor moderne warmwater- en verwarmingssystemen.

just get it and stop second guessing
Color: White, Color: White
I reallllly love this chair. I almost talked myself out of it because of some of the bad reviews here and there but i’m glad i listened to a majority of the good reviews, because this chair is perfect. shipping: it was super fast. it came 5 days earlier than expected. I got it on a Monday when it said it’d be here on Friday packaging: double boxed and bubble wrapped. Didn’t find any dings or scratches on anything. all parts were there including instructions assembly: my boyfriend put it together in 40 minutes. We didn’t have any issues zipping up the back cover like other reviews said and he said it was easy instructions to follow, and easy to put together. size and comfort: it’s bigger than the pictures let on! I’m 5’3 135lbs and feel like I’m sitting on a giant cloud. The comfort is 10/10. I just had a chair with basicslly zero butt cushion which i cannot have while working from home 8+ hrs a day in a chair. Comfort was the most important for me and I finally can’t feel the flat seat under me. I can’t express how comfy it is. Functions: can move the arm rests up and down. adjust the back to tilt all the way back to a sleeping position or fully upright which i didn’t even realize was a function! The only thing with the armrests; if you’re wanting your pet on it (like advertised) when the arm rests is put down there is a big gap that isn’t comfortable for animals (as pictured) so I have to put a blanket or pillow there for my small dog to lay comfortably. I’m obsessed with the fact I can sit cross legged, normally, laying down, sprawled up, or legs up. I have room to sit however I want, and the foot rests helps a ton with feeling even more comfortable. Overall, I’d get this chair 10x over. Not only do I work from home and spend hours in a chair, but I spend additional time playing video games so a good quality chair is very important to me. This has began to help fix my posture and back and neck issues. Get it!!!

If You Sit Weird Like Me… Just Buy This Chair
Color: Galaxy Black
I work from home and spend a lot of time sitting for hobbies like Legos, PC games, and crafts—so a comfortable chair is a must. I LOVE this chair so far. I’ve always struggled to get comfortable in traditional office chairs, and the ability to move around is really important to me. With this one, I can easily cross my legs, use the footrest to stretch out with my knees bent, or just sit normally. I’m 5’4”, so my feet don’t quite touch the ground, but that doesn’t bother me since I’m constantly switching positions anyway. I’ll probably add a small pillow for extra back support and maybe fold a blanket for a bit more seat cushioning. It’s comfortable overall, but after long periods of sitting, you might start to feel it. The black sparkle version is MUCH cuter in person, and I’m so glad I went with it. A lot of reviews say, “don’t think about it, just get it”—and honestly, they’re right. I debated for a couple weeks before buying, and I have zero regrets. Assembly was easier than I expected. I tend to get frustrated putting things together, but this was pretty painless. One tip: check inside the cushioned back piece for the extra headrest part—you’ll need it to attach to the hard back before inserting it into the cushion. Once I figured that out, the rest was simple. The chair is a bit larger than a standard office chair and can feel a little bulky depending on your desk setup, but I actually like the extra space since I move around a lot while sitting. It feels sturdy and well-made. It’s also slightly warmer than a mesh chair, which I personally love because I’m always cold. I am just happy to find a chair that feels comfortable like a recliner and movable like an office chair.

Great chair
Color: Pink
I love this chair! I use it for streaming and working on making jewelry! It’s very comfortable and I love that I can sit different ways in it! I can stream longer than I could in other computer chairs I’ve had! I definitely recommend this if you have to sit for a long time but like to sit in different positions! The instructions were a bit confusing but I did figure it out! I have had to spot clean it a few times because of kids and pets but the material has held up! The back is very comfortable and supportive! I like that I can adjust it! Great chair for the price! It’s held up well and I like that you can adjust the back!

Good office chair for the money
Color: White
It is a good quality chair that is comfortable and aesthetically pleasing. The arms aren't necessarily big enough to hold our cat - but that's because he's fairly large by cat standards. The arm rests moving is definitely nice and provides lots of opportunities to 'setup the chair' in a way that works best for you. The instructions were relatively easy to follow (take your time and think it through to make sure you have everything 'aligned right' at first) and the chair is sturdy and holding up well.

Comfortable. Great Value for money. Easy to assemble. Great customer service.
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I've been looking for a new chair to replace a cheap $30 chair i bought off of Amazon last year that had been killing my back and shoulders. I wanted something in the $150-$200 range and settled on the M18. Shipping was a fast 3 days with Prime and the box arrived in great condition. All parts were separately wrapped or in their own boxes. Came with all hardware and nothing was missing. Assembly took me a little longer then normal because i have rotator cuff injury in my left shoulder so that arm is mostly useless. The most difficult part for me was attaching the wheels to the base. Other then that it was simple. Once the chair was assembled i sat in it for the first time and started making my adjustments with the recline feature, armrest level along with the headrest. Next i reached around for the lumbar support knob and tried to adjust it but with my bad shoulder i decided to just get out of the seat and turn it around and adjust it with both hands. After spinning the chair a round to get at the lumbar knob i noticed a large crack in the plastic in the middle of the back of the lumbar plastic piece. I had not made any lumbar adjustments yet so i assumed this is how i received it. The lumbar support comes preinstalled to the backrest so it either was damaged before or during the shipping process. Either way it was damaged before being delivered to me. The lumbar support still functioned properly but it was still broken. I decided to contact Sihoo's customer support that came along with the installation instructions regarding the damaged lumbar piece. I received a reply the next day and after sending them some more info about my order and a couple pics they shipped me a replacement part which took a week to arrive. I swapped out the damaged part and after owning the chair for a week so far i am really happy with my purchase. Im about 5'10 180lbs. At its highest height level my feet reach the ground comfortably flat footed. The backrest fully covers my back and the headrest adjusts very well to sit on the back of my lower head/upper neck. The armrests only go up and down....not forward and back or tilt inwards. This is fine for me as they are grooved to fit your forearm while sitting at your desk/keyboard. The armrests are also a soft cushioned rubber material...not a hard plastic. The mesh of the backrest and headrest are good material and seem well made. The seat is very wide and the cushioning is firm which i prefer. Usually more firm cushioning seems to last longer and hold its form. The base of the chair is VERY sturdy and made of all metal. My chair is on carpet and holds its position very well. As far as recline goes you can set it to recline all the way back, half way or lock the chair in the upright position. You can also adjust the resistance on the reclining feature. So that being said im very happy with my purchase. It arrived with a slight flaw which the company corrected in a fast manor and was very polite in their customer support. I personally don't have a lot of experience with many office chairs and have never used a high end chair($500-$1000+) chair before to make any comparisons. All my chairs for the most part have been from local stores like Staples or Office Depot. Id recommend this over anything they carry in this price range....and i went and looked at their products before buying this chair as well.
