Frequently asked questions

I am looking to replace a wall mounted multypoint heater for my Daughters flat I am told I need one with a flu adapter can you help, Im desperate.
If a flue adapter is required it suggests the boiler is gas fired. All our water heaters are electrically heated and do not require a flue adapter.
will this system work in a caravan through a 9amp system
The water feed to the Speedflow needs to be from the mains water supply to require the expansion vessel and check valve. To operate the heater a 230Volt mains supply is required which will require 9amps current The heater can be filled from a storage tank, in this case the expansion vessel and check valve are not .
