Common problem is that boilers don't produce enough hw. I want to install an 80g electric hw heater that is fed from the boiler domestic hw. Is this do-able??? I'm thinking that instead of cold water feeding the electric heater why not feed it with the boiler water so that the water is preheated thus saving on the electric bill.
