Getting plans done for new build house and thinking we might need to go down a greener route,
anybody using air source heart pump? The house 1 1/2 storey with UFH on both floors well insulated.
I want to get it right and avoid costly mistakes. Have done 1 new build before using oil fired boiler and UFH but architect says I might not be allowed oil due to new regs
Most of tasmania, why you think it's greener?
All depends on the system, some are noisy, some just blow air at you, some of the ducted are different, not really a fan after all the years of them
Reverse air-con pumps is a better name.
Have you mains gas?
Have you done a more passive (imore nsulation, passive heat gain, air tightness etc) and minimal electric heat vs a heat system such as ashp or gshp or oil ch or gas ch? Worth doing the calcs.
Remember that they become less efficient as it gets colder, particularly below zero.
We are going GSHP, well we will if we ever get planning (now 6 months overdue a decision!).
its rural location so no mains gas, Oil would be my preferred choice as fairly cheap system to install and it works. Architect saying it will be difficult to get Oil heating through building control and is advising air source heat pump running ufh. The house will be very well insulated.
Waiting to hear back about sap calcs etc
andyl I feel your pain. Planning building warrant etc just seems to take ages nowadays.
The easiest bit is the building!
Define very well insulated....Passive House / Gold?
Where geographically is the house?
I have a daikin hot water and central heating Ashp system fitted in my house (very small 1 bedroomed semi detached bungalow with **** all insulation in Galloway) and it’s shite, actually I’d go as far as saying it’s ****ing shite. It’s fine for hot water (semi tepid), as long as you don’t wish to have a bath then do not expect to have any any hot water for at least 4 hours afterwards, and if the outside temps drop below 10dg then it’s a bit hit/miss as to whether the heating will kick in when you switch it on (I can’t afford to have it on all the time so I only switch it on when I need it), at the moment it’s -2dg outside and I switched the heating on when I came home at 6pm tnight as the temp inside the house was 13dg, 4hours later the radiators are still cold but I can hear the outside fan is whirring away merrily whilst doing **** all but burning electricity.
Thank god I have a wood burning stove fitted as otherwise I’d be sitting here freezing my bollocks off, the council have been out perhaps 6odd times over the previous year but can’t find any problems so yesterday I’ve told them if it’s not fixed by the weekend then I’m tearing the entire system out and fitting a back boiler to my existing stove (I’m not, I’ll get my plumbing mate to do it) or fit a new stove/back boiler.
