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

[Ivor Windybottom]

Heat pumps main down fall is when poorly spec’d and the temp drops below the point they become useless.

Heat pumps are best suited to a low load, so today they would be happy doing next to fek all. Much like central heating l

All just myth and nonsense. If there's any glimmer of truth in all this often-quoted rubbish then it's based on heat pumps 10 years ago, or badly installed ones with crap plumbing and radiators.

We've had our system a year. It's worked absolutely flawlessly through the winter, kept us snuggly throughout and we've had much lower bills compared to the electric rads we had previously. It just works.

weather compensation controls can lower the temp. This is the problem with air to water heat pumps on retro fits. They really are not designed for this purpose, the new build houses are better suited and the whole system needs to be designed for these more than trying to retro fit them into older properties. They need a lot of design and calculations for a retro fit.

A heat pump doesn't know whether it's in a new or old house, it just squirts warm water into a pipe, very efficiently.

If you mean an existing heating system then that may be an issue, but it's not what you stated. Ours is an all brand new system in an old house.

designed and fitted well is a big factor, ours could have been much better but we decided to go with air con as we wanted the cooling and so we spent the money there. So glad we did.

Both types of system are good, both work well and have different pros and cons.

We'll both be snug and smug as a smug person on the internet when the gas stops.

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.

A bigger radiator won't increase the input heat, no matter what. If the house needs greater temp's, heat pumps fail miserably.

That's a bit mangled! IMHO.

Have you got one or is this what you have heard?
