Pros and cons of conventional and combi boilers...

Anonymous user 28/02/2024 - 2.34 PM

We have just moved into a 2 bed semi bungalow (with one bathroom) and currently have a (non-running) conventional boiler. We were planning on changing it to a Combi. However our long term plan is to extend the property (inc. building into the roof) and more than likely have at least 2 bathrooms/en-suites. I am particularly interested on the following points: 1) Is it easy to change a conventional boiler to a combi? 2) If we have a conventional boiler, can we still have a shower that heats water straight away (like a combi boiler would) ? 3) Would we be able to have a pump on the shower with a combi boiler? 4) Would it be acceptable to eventually move the tank downstairs? Many thanks

Are you a tradesperson and able to answer this question?

Taking each point in turn: 1. Changing from conventional to combi should be straighforward BUT the water and gas supplies will need to be checked for pressure / flow first. 2. You could install an electric instantaneous shower that heats up on demand but, like the combi boiler, the water and electricity supplies will need to be checked for suitability first. 3. If you have a combi boiler there is no need for pumped shower supplies as they will already be high pressure. 4. The hot water cylinder could be moved downstairs (space and accessibility permitting) Hope this helps.

Hi, There is a combi boiler which has a small storage tank built in, Its rather large and unsightly but it will give you instant hot water at two taps. It wont run two baths but its great to get around everyday combi downfalls. A great one is the Vaillant 937 store, highly reccommended by myself, Google this boiler it should suit your needs but bear in mind they are very costly.
