Underfloor Heating Wet or Dry with Solar panel
Comments (4)Independent of the UfH the use of Solar PV is definitely a good idea. You'll have to significantly oversize it though if you want to make an impact on winter time heating, because the winter sun even on a good day won't give you more than 5% panel efficiency averaged over sunshine duration. Electric UfH is cheaper to install and usually argued to "switch on fast" and to be "100% efficient". The latter two are marketing though - the switch on time depends on the thermal mass (thickness of the screed; set electric into thick screed for heat retention and it won't react faster than wet UfH) and what gets warm fast also cools down fast. All direct electric-to-heat is 100% whether it goes into the water for wet UfH via immersion heater or into the electric UfH. Remember water is the perfect heat store; heat it up during the day and you can still use it the next morning (traditionally, heat it up on economy7 during the night ... how solar PV can change things). Wet UfH has the advantage that you can choose the main heating system. If you're all-electric use a Heatpump to boost what you'd get from direct electric alone. Otherwise use the gas boiler you have with a warm water storage buffer tank (and run the immersion on PV). Electric UfH has its place; a bathroom refurb or a garden room; for a major project, entire floor or all of the house, I'm not a fan. Wet is much more flexible there....See Moretile floor with underfloor heating - ca I put vinyl on top?
Comments (6)I doubt there's any logical reason for not being able to. The only thing I would imagine it's going to do is affect your heating. The underfloor heating would have to then travel through two types of flooring, thus, you may have to turn the heating up in general to achieve and acceptable ambient temperature. Just an opinion ...............i'm not an expert in underfloor heating - I'm sure there are professionals on here that are, so maybe they'll jump on the post?...See MoreSuspended timber floor: insulate from above or below?
Comments (6)Thanks Jonathan. I was wondering about that. Our architect specified Celotex in the building control plans so I was investigating that, or similar products. I'm not sure if that decision was due to fire retardance or to other issues. Because I'm doing most of the project management it's important to know the order in which everything needs to be done, hence the question about what can be done above or below floorboards - it really does affect a lot of my decisions. I will look into foam as well as Celotex....See MoreKarndean flooring and underfloor heating
Comments (1)We have wet ufh and Karndean throughout our ground floor. The ambient heat to the rooms is really good. Obviously a tiled floor would spread the heat more evenly across the floor, but the flip side is that tiled floors are cold in the summer when you don’t have the ufh on. So, one of the reasons we chose Karndean was that it would feel warm underfoot all year. You need to make sure the correct adhesive is used so it doesn’t melt when the heat is on....See More
