Air to Air Vs Air to Water Heatpumps. Now closing the gap.

[MNW67]

It doesnt quite work out like that if the system has been designed correctly, in these examples you would compensate for this by a weather compensation temp control where the water temp is lowered to avoid this and also a buffer tank can be fitted to also prevent this, our old system had neither and suffered through poor design, the cost of upgrading it wasn't worth it as it was cheaper to take it out and replace it with a trad gas boiler.

Buffer tank correct but WC arse about face.

I am no expert in them. forgive me.

Me neither. Forgiven. OMG. Exactly. Think on...!!!!!

I am happy to have air to air as it works for us, Lena and I are a cool couple and need the features that air to air gives us in order to maintain just how cool we are.

Since looking into these heat pumps have you had any education by looking into their efficiency?

I'll stick with a combi boiler, I can afford the running costs.

Oh I mean my friend will.

Yes heat pumps are not for old fashioned types.

I will bet he wears Y fronts too.

It gets so confusing because there are three different efficiencies with ASHPs; vs water temperature, vs outside temperature, vs compressor speed.

well to simplify it, look on it as if you put 1 kwh in, you will get around 4.5 kwh out, that is some efficiency but obviously on a correctly designed system.

try this, I know you will read it and take it in.

You’ve managed to over look “heat loss”

That’s the calculation professional heating engineers use. Like me!

I’d take you on, but your the poster who said wheel nuts aren’t needed..

Oh dear. I'll try to explain it in terms a pretend heating engineer would understand...

If your heat loss remains exactly the same, the weather stays the same, you're wearing the same coloured socks and everything in the world is identical to how it was yesterday then...

If you intend to reduce the flow temperature then you need to increase the size of the radiators.

It's just simple, basic physics. I don't know how I can make it more simple to understand. A radiator conducts heat from the water to the air. If that water's less hot and you want to make the air just as hot then you need more surface area.

Absolutely no idea what your wheel nuts thing is about.
