I am in the middle of getting quotes for a new central heating system for my 2 bed 1st floor flat. I am thinking of putting in a Baxi duo-tec 28 he platinum, with a ADEY MAGNACLEAN PROFESSIONAL 22MM, because the boiler will have to be positioned in the front bedroom I am thinking of using a GRUNDFOS CONLIFT AUTO CONDENSATE PUMP to pump up into the roof space and across to the waste pipe. I would also like to use a Danfoss Randall TP5000 Si 5/2 Wireless Programmable Room Thermostat with RX-1 Radio Frequency Receiver. my first question will this combination cover my particular type of abode.
the 2nd part is to do with the rads I am looking at putting 5 rads fitted with with a heated towel rail for the bathroom all fitted with Drayton TRV4 Thermostatic Radiator Valves. I am thinking about putting in Aluminium rads because I have heard they tend to be more efficient, although alot more expensive, therefore I am trying to work out the btu/watts so that I can buy the correct rad size. As all the online btu calculators seem to come up with different totals is there any better way of calculating btu/watts.
Anyone who could point me in the right direction would truly be appreciated
Your 5 rad system will be well covered by the configuration you mention.
As far as sizing the radiators, the use of a Mears calculator would be most accurate, this rotary disc takes into consideration all heat losses and gains that require to be allowed for in domestic premises.
Unfortunately I donn't have a Mears, perhaps another member of the forum may offer assistance with this.
