All your heat pump problems solved by -- a plate heat exchanger in a plinth!
@iaack of course, you're right, but that's not the market the OEM of 'Heat Saviour' is targeting, They are targeting retrofit ASHP heat pump market, so it clearly says in their marketing literature. I can't see this product offers any advantages to that market, save purely the convenience of the retrofit installer. The home-owner or occupier is the party disadvantaged, with a built-in thermodynamic inefficiency and additional running cost of a second circulator pump that in many smaller homes would not be needed.
Sadly we don't really do district heating in the UK to any great extent. Shame, as larger air, ground or water source heat pumps serving multiple dwellings offer efficiency advantages. Most houses have their own CH and DHW fired combustion combi boiler. If the UK is committed to replacing those in pursuit of Net Zero 2050 and to decarbonise domestic heating, then replacement products should compliment best practise and best efficiency. 'Heat Saviour' doesn't, it lowers the SCOP potential of the ASHP by adding a 2nd PHX in the design in addition to the one in the heat pump. It increases running costs, by requiring a second circulator, and by raising the design LWT temperature on the primary circuit side to achieve the required flow temperature on the secondary side.
@allyfish As you say, all the ‘plus points’ and ‘advantages’ are very much for the benefit of the installers - the costs to the end user would appear to be irrelevant! It really is a shame that the advertising / sales fraternity have such finely tuned aims (that rarely if ever extend to providing any advantage to the end user!).☹️ Toodles.
