Debra Posted September 28, 2012 Share Posted September 28, 2012 OK I'm sold! We fancy having a bath too so a chauffe eau would probably be better than the combi oil boiler alone (no hot water tank) to fill that. Can I ask a probably silly question AnOther? Where can you put the chauffe eau in the system? Does it have to be next to the oil boiler or can it be anywhere along the line of hot and cold water pipes? I ask because we have no room next to our boiler but we would in the bathroom. Are you allowed to have it in the bathroom? Link to comment Share on other sites More sharing options...
AnOther Posted September 28, 2012 Share Posted September 28, 2012 Plumbing wise you can put it almost anywhere, you need access to the hot and cold feeds and a drain for the group security pressure relief valve to vent to.In the bathroom - I couldn't say for sure if that's allowed under current regulations, I would guess yes.

Kong Posted September 28, 2012 Share Posted September 28, 2012 My heater has a big fan and makes a lot of noise. Also the heat pump generates cold air. I guess you will have a cold bathroom!Kong Link to comment Share on other sites More sharing options...
AnOther Posted September 28, 2012 Share Posted September 28, 2012 A modern chauffe eau has no fan nor any other moving parts and consequently is silent.Who mentioned heat pumps too, nothing whatsoever to do with a chauffe eau ? Link to comment Share on other sites More sharing options...
Kong Posted September 29, 2012 Share Posted September 29, 2012 Sorry I'm confusing the issue, I have pompe a chaleur which is more efficient still - about one third the cost of chauffe eau. Link to comment Share on other sites More sharing options...
AnOther Posted September 29, 2012 Share Posted September 29, 2012 [quote user="Kong"]Sorry I'm confusing the issue[/quote]Yes, and you really should have left it there, unless you trying to argue that a pompe a chaleur is in some way an alternative method of providing 200+lt of domestic hot water on demand for €10/mth ?If so then please do elaborate.

Kong Posted October 2, 2012 Share Posted October 2, 2012 Yes it is. I have a 300l tank with a heat pump on top. Just as with reversible aircon/heating systems enengy is extracted from the air (in this case) and used to heat a refrigerant which in turn heats the water. For each kw of electricity used up to 3 kw of energy can be generated though this level of efficiency is rarely achieved. So it is inevitable that it is cheaper to run than conventioanl ballons. However the capital costs are inevitably high. Also under some circumstances you can claim tax relief, though I've never tried. Link to comment Share on other sites More sharing options...
AnOther Posted October 2, 2012 Share Posted October 2, 2012 My apologies then.I am not familiar with the combination you describe so thought that you were talking about an ordinary pompe a chaleur which obviously has no water storage capacity.

Kong Posted October 2, 2012 Share Posted October 2, 2012 I will email you a link to the company that supplied my heater, not exactly the same as mine though. Link to comment Share on other sites More sharing options...
