ASHP or MAINS GAS?

[Reg Man]

On a personal view point. I have Daikin Altherma ASHP in an older not brilliantly insulated house and in comparison to my old house which was smaller and very well insultated, up to current insulation standards with mains gas condensing boiler, my fuel bills are cheaper now with the ASHP and all electric. I run the electric on an economy 18, so cheaper night tariff but also cheaper daytime tariff for the ASHP. I am considering putting 16 PV panels on the roof.

I agree that they are noisier, but not any different to an air con unit. So wont be great for everyone. My ASHP is fine as I do not have any nieghbouring houses close by and I can't even hear it when indoors.

That's great to hear. Issue with tarriffs is I think a lot of the energy companies are becoming aware. I'd heard economy 10 was the best for heat pumps but not many offer it. Ill have to look at 18 as I'd not heard of that

 

[Reg Man]

I am nt sure if economy 18 is available anymore. I managed to get it, but don't think the suppliers are to keen to give it out. Probably because the day time stored heat for the ASHP cheap rate which is only 1p per kW/hr than the night time rate.

You saying you get daytime rate at 1pkw? If so that's amazing

No! 1p more than the night time rate. Night time rate 6p day time stored rate 7p.

Ah right, that's still a very good deal, I'd hold onto that forever!!

What fuel will you be replacing? The system will pay for itself much more quickly if it's replacing an electricity or coal heating system. Heat pumps may not be the best option for homes using mains gas.

They all are if the customers expectations aren't set right. The move a lot of air and this constant'ish noise can be intrusive.

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

I am constantly surprised how quiet some of the new gas boilers are, the ideals and remehas in particular

 

[Reg Man]

Sorry could'nt hear that my ASHP just kicked in:wink_smile:

Clearly I'm not. 🙄

The ideal vogue is amazingly quiet - practically silent.

Btw, old says it all. Maybe time for a change to a ASHP? 😉

I am not going to read below because a really switched on associate of mine
who has vaste experience in the HVAC industry installed a ASHP in his sons house
really just to see ..........and he said to me last Sat that it was rubbish and a total
waste of time and money- his men would not have installed it incorrectly

Hi and thanks for reading my query

I am renovating an terraced Edwardian house which will be well insulated. The gas boiler is old and the entire Central Heating system is a mix of ugly rads, normal piping and microbore, in short it needs replacing.
I will be fitting UFH regardless of the ASHP/Gas question as I prefer it and the floor boards need lifting and insulation installed anyway.
We have a mains gas supply.
Is an Air Source Heat Pump a better choice than gas?

Heat pumps will work in ANY environment but must be sized correctly.

 

[Gerard17]

Heat pumps are only any good in new builds and we're gas is not available at the moment gas all the way. In a retro the insulation has to be to the maximum but it still wouldn't be worth it. A little air source heat pump is good for a conservatory as it can blow hot in the winer and cold i the summer

obviously it hasn't been installed correctly, they're probably just a bunch of pipe stranglers who haven't got a clue

If there so rubbish, why does my ASHP work so well and efficient, along with 1,000's of others? Your associate must have missed something along the way, a really expensive "just to see".

 

[Centralheatking]

Fair play to all - perhaps my opinion because of my friends experience is premature.

We will get the system rated and compared and report back on this forum in due
course.

Thanks 4 all your input

You are extremely misguided. I suggest you fit a few in very differing situations before making comments that make you look more than silly.
