Hot water return on heatrae sadia megaflow

[warmfront]

I have a question regarding a hot water return facility on unvented hot water systems. can anyone tell me what the benifit is of using a bronze pump to creat a ht water return. Is there a scimatic diagram i can acces to explain this to me as i am having it fitted and don't realy understand. just want to get my head round it,

Thanks!

The idea is that you create a loop of hot water flowing around the house and back to the cylinder.

Whenever you open a hot tap the water comes out hot almost immediately. The drawback is the pump uses about 10p of electricity a day and the heat loss from the pipes costs about 20p to 50p per day depending on how well insulated they are.

In an ideal world the pipes would be well insulated and the pump timed to run for five minutes every 20 min.

It seems odd that you are having something fitted when you dont seem to know what it is!

Not difficult to do .
Athough a 10 second pump run time in every 35 minutes will work fine for most domestic applications provided their is good lagging on the pipes.
