We currently have a 15 year old Vokera combi boiler. We currently have one bathroom and the shower just runs off the bath mixer tap and is ideal for what we need. However it sometimes struggles to fill a bath with hot water.
We are putting an extension on which is going to add an en-suite and a downstairs w/c as well as morea study, bedroom and family room so obviously more radiators as well.
What type of boiler should we go for? On doing research there seems to be different camps saying bigger combis, or the newer condensing type that have a hot water tank but much more efficient.
One of the showers will probably be electric so wouldn't imagine that both would be running off the one boiler at the same time. Dishwasher, washing machine are both cold fill.
I got the combi at the time as this was the "new" way to go, no need for hot water tanks and surely you can't get more efficient than only heating the water you need? But a lot of blurb on the new systems with tanks say they are super efficient as well?
Whats thoughts of the experts on here? Is Mr Devon within our midst yet?
