Refrigerators, freezers, (& heat pumps in cooling mode) produce heat, can that heat be used to heat the hot water cylinder?

Why not a fridge freezer linked to a hot water supply?

Should external heat pump units be south facing in the summer (when cooling) and northfacing in winter (when heating)?

Provided a suitably sized hot water cylinder and Hot Water heat pump are used a considerable efficiency gain could be made by only running the heat pump at the warmest time of the day. Are the heat pumps tested fitted with such timers?

This is an interesting item. However, it would be so much more useful if the data from which your conclusions/ results were drawn made available. e.g. what output is available from each unit at a range of temperatures ant he efficiency at that point. I realise that this is more information than is required by many, but the web site could have a page to provide more technical information.

A great article. I presume this could, with suitable tempering valves for the cylinder output, be used for home radiator-based heating, which seems a missed opportunity so far by both water heatpump and solar panel suppliers? I recognise radiators are an added cost but they are far less intrusive than the usual split sytem heat pump solution. Are you aware of anyone supplying such? cheers Doug

How does the energy savings of Heat Pump hot water heating compare with instant Gas Hot water heating.

With Gas, you do not require a hot water cylinder.

You would probably be impartial enough if you had links to manufacturer/suppliers since e.g. there is no result for Econergy HP4000 LT when searching on line. Cheers Tom
