Hi,

The existing tank is a Rolyat Calorifier which has 28mm pipes linking
it to the BBU. It would mean extending these pipes about 6 to 8 feet up
to site a new tank in the loft. I would imagine that the current run
for these pipes is about 10 feet vertically and 16 feet horizontally.
The Homeglow BBU is set on the lowest thermostat setting and has no
problem providing hot water to the tank although the conduction system
is a little slow when waiting for a full tank from cold. It would be
nice to have a pump on the new system if that's possible.

Thanks for all the help
Kind regards and best wishes
Phillip
