Try and get this right! So the control valve on the UFH is set at 35 deg and the hot water is set at 46 deg on the panel. With no heating on at all, consumed energy for July is 93 KWH and delivered energy is 134 KWH,so this is poor for running the DWH and the weekly legionaries cycle,no?

Flow temp is 46 degs and we have about 14 zones over the two floors. Temps in all rooms in winter avg 19/20 degs with all heating turned off between May and September. COP on this heat pump shows 3.36 so getting nowhere near it atm. House was completed in 2019,so not like it’s an old house 🤷‍♂️

Been using an Ecodan 8.5 k for heating and hot water in my 180 m2 home,UFH on both floors. Looking at the figures for 2021 just wondering if someone can tell me if it’s working efficiently Figures are: Consumed energy 4846 kWh of which 1397 kWh was DWH and 3449 kWh for heating Delivered energy 9456 kWh of which 2780 kWh was DWH and 6676 kWh for heating about to build the same house shortly so just wondering if another heat pump is the way to go 👍

I get that about the feathering but the claims from Cemfloor that it’s laitance free and perfectly level lead me to presume that it might be good enough for the lvt. All I would say is that it’s a lot quicker to install but the contractors have let me down badly with not having any crack control at the doorways so an expensive lesson learned!

Install in my house in Scottish Borders. My warranty guy asked for joints in the doorway but they were adamant they weren’t required with this product. Tbh,I presumed the floor would be smooth enough to lay the lvt straight on to but the flooring contractor says it will need a further screed at a cost of £1300 on top of the £4200 I’ve paid for the cemfloor. Did my last house with sand cement myself and had minor hairline cracks but nothing like this. Tried to get McGrath’s Congress involved who supply the aggregate but they want nothing to do with it. One expensive f**kup!

Had cemfloor installed in November over 2 floors . UFH went on at the end of January and have large cracks at every doorway,some cracks 6 ft long going into the middle of the floor. Contractor been back to fix cracks with resin but completely pissed off with the finished result! Heating temp increased 2 degrees every second day so this isn’t the cause,just bad workmanship through not installing joints at the doorways. Any one else had problems with cemfloor?

In any construction trade it’s all down to the individual tradesman what standard you get. Block built or timber frame both have their merits but if your bricklayer/joiner’s a numptie your on a hiding to nothing! I'm a bricklayer myself and I’ve built around some dodgy kits, 50 mm off the plumb from floor to eaves but I’m sure there are some bricklaying horrors to match
