Last year I spent many thousands on a new condensing boiler and new pipework to old radiators (the old space heating system was a 1 pipe system). At the same time the new pressurised (megaflow) cylinder was connected to the bathrooms and kitchen and 2 bathrooms were completely re-fitted. Although I had made it clear that I did not want a long time delay in drawing off hot water from taps in bathrooms and kitchen (thinking the plumbers would install a secondary pumped h.w. circuit) in the end that's what I got. They said it would have been too difficult and I have to say they may be right because of sundry access problems that I don't need to go into.
I'm not going back to those plumbers as they took forever and never turned up when they said they would.
Now I'm thinking of fitting an instantaneous water heater to heat the kitchen sink water (otherwise it takes about 2 minutes to come through from the Megaflow). The water pressure is good - an accumulator has been installed.
Looking on the internet, I see something called a Redring unvented water heater, 12 kw, which is said to be the highest rated of its type in the UK. The site also says it is for fitting on the cold water supply.
My question (at long last) is, can this heater be fitted on the hot water supply, so that when it is used, if hot water is coming through (eventually) from the Megaflow, it runs through the unit which doesn't have to use energy to heat it again. But if the water is cold (that's for the first couple of minutes) the electric water heater works instantly.
Any bright ideas?
Best wishes,
Paul
