Combi, Megaflow or Replace Traditional System Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

The conventional heating system in our 2-bed flat needs replacing after many many years. Currently we have a pump installed for each bathroom to maintain good flow, this works very well.

We like the idea of a combi as it means we can remove the 2 tanks and use the space for storage etc etc. However our concern is that the pressure from the combi will not be enough if both bathrooms were being used at the same time. And alas there is no way of trialling before you buy?

Megaflow seemed an appealing option but the plumber who came to do an emergency repair on our system recently felt that our mains flows was not adequate for megaflow.

Any advice on what the best option might be would be great. Thank you

For a 2 bed flat a combi would normally be ideal. But as you say may not be able to cope with 2 showers at the same time.o you use 2 showers at exactly the same time ?

You could fit a condensing system boiler, with tanks and pumps the way you have now.
