Discuss ASHP or MAINS GAS? in the Plumbing Jobs | The Job-board area at PlumbersForums.net
An air-source heat pump is a good choice. Yes it is a more expensive little bit but well worth.
Me to! 4bed 1960's house on ASHP Total utility bill cheaper than total N gas and electric bill on previous smaller 4 bed 1990's timber framed house. Figures speak for them self. I was at first very sceptical about ASHP, but I can't knock it having lived with it for two years.Shows how much you know! You don't need buffers or llh on most systems! I've fortunately got a few units that have over 12 months worth of running costs and they're all smashing the oil running costs! Mine at home is actually running my 4 bed detached 1970s house cheaper than I ran my old 1995 3 bed semi on natural gas, afraid you can't argue with figures.
Only know that my last house had full NAT gas HE system boiler with all controls including separate zones for upstairs/downstairs, optimiser the lot and my utility bills are now cheaper in a larger property with less insulation factors with an ASHP. I do admit that they are less convenient to use than a gas boiler, but I am pleasantly surprised by its efficiency, My only other option is OIL or LPG, so happy days for the ASHP.But any figures you chaps are giving are for the running costs of installations of ASHPs. You don't know the running cost of the same property with a HE modulating gas boiler, or a correctly installed system with a ASHP - including a buffer tank.
There's no way a ASHP, even an inverting CO2 one, would touch a Nat Gas modulating boiler. Blue Flame Rules!! Get over it Greenwashers & tree huggers!!
LOL!!
I see the misinformation squad are in tonight then...
Do you know perchance what these weeks costs you in Leccy Reg??It worked fine all last winter with 3 weeks of snow on the ground.
I'm pleased to hear it mate in every regard.Also never sold a car in my life, left school at 16 and did 5 year apprentice inc city and guilds, shame not many bother nowadays. Just like the story I've heard of a biomass quote on a 3 bed insulated semi detached 21kw! More like 6-10kw max. The sharks will be swimming now the rhi is out. Also turned down 2 ashp vs gas this week as it just wouldn't pay. Got one as they want one full stop and have pv so each to their own I suppose.
Can't give you figures for the cold weeks but total electric for the year ÂŁ1,400. Thinking of investing in some PV panels, think I can get about 20 panels on the south elevation of my roof, also have a wood burner and unlimited supply of logs in my woods.
are you trying to tell me that gas boilers are totally silent if so why does my old worcester combi wake me up at night when the pump kicks in for no reason, at least with a heat pump they are outside and the noise is barely audible even when standing next to them
Thats very good home running costs Reg mate. Careful with PV panels, there's loads of Sharks selling them. Also, your return on investment will deminish as any of these panels get older, they just don't produce the same power as when they're new. The technoligy has not been around long enough to prove what they'll do in 20-25 years, so don't listen to the Greenwash BS!!Can't give you figures for the cold weeks but total electric for the year ÂŁ1,400.

I would like to tank all for your input here its been interesting to read .... please give more information about a ASHP as what is so much to know about there installation ? I have never worked on one just been to a property where Mick aka "unguided" (was a member here ) worked and he showed me the installation and we had a cup of coffee and a good 3h of chat about them ! Did not see any rocket science there tbh .....
I just would love to receive more info about ASHP , and if you have one installed somewhere or you are in progress doing it I would love to come along and take part of the install (for free) ! I am to book my self with WB for there 3 days training for the ASHP but would love to see it in action before I go there
Good postes there Dickies
That's why I've held off getting PV sooner. Thought if I wait around a bit, the quality and effectiveness of them will be proven and the price may come down a bit yet. One of my Pals had 16 put in 2 years ago and he is well happy with the saving and returns. He worked out it was better than having the cash sit in a savings account even if the capital is a right off in 20 years time.
Time will tellWhat happens to your pal's investment when the panels are producing Jack Sh.t in five years time?? Has he still got the Warranty for the panels that our Chinese friends manufactured & a crack legal team in China to drag them through the courts over there???!! Tell him from me, good luck with that!!
Most Chinese heat pumps are only a 'screwdriver job' in China, with lots of Yanky & Jap components.
Would one of these air source heat pumps be efficient with the overlay type of underfloor heating or is it best to run it with more traditional in screed type? Property was built early seventies so i imagine no insulation under screed. I dont want to dig the floor up really, so i suppose its a choice between the overlay and rads.
The heatloss through the floor can be minimal, well, when there's quite a steady geothermal temperature that may explain why. Check out castellated insulation boards, they can be quite cheap & many you can just fit a chipboard floating floor over. Not ideal, but if you beef up the insulation in the walls & roof, it could be an option. Regardless, if fitting any ASHP I'd recommend some form of inexpensive supplementary heat; Multi-fuel stove.Would one of these air source heat pumps be efficient with the overlay type of underfloor heating or is it best to run it with more traditional in screed type?
