Hello. Thank you in advance for any advice. It is much appreciated. I am interested in converting our home from oil central heating to a gas combi-boiler. Background/Existing house system: We had a gas supplier promotion slipped through our letterbox saying that gas is available on our street and we could contact them if we were interested in converting to it. Our townhouse is currently fed via a large oil tank that is located in our back yard. The oil tank connects to an internal room on the ground floor where an oil boiler is located. It has a flue through the roof. The system has an insulated tank on the first floor. The system also has a water storage tank in roof space (above second floor). We have two showers. The shower on the second floor is an Aqualisa Aquastream pressure shower unit. I assume to increase water pressure. The shower on the first floor is an electric pressure & heating shower (it backs onto insulated tank/drying cupboard). Elsewhere, there are 7 handbasins, 3 toilets, 1 sink, 1 dishwasher & 1 washing machine.
From my research I understand the following:
1) The combi-boiler may cause water supply issues if more than one fixture is used at the same time. I have a 4 person family, so is this a big issue? Is there any way around this?
2) The electric showers may need to be replaced with normal shower taps/rose. I'm ok with this but there is an additional cost I need to allow for for replumbing & plumbing fixtures.
3) The roof tank will no longer be needed as the combi-boiler will suppy a water pressure comparable to that from the street. Will this pressure be enough to go up 2 storeys?
4) The insulated storage tank will not be required as hot water is delivered direct from Combi-boiler.
If there is any concerns I should have for this, I would love to hear them. And if anyone give me a rough idea of overall cost for install in Northern Ireland.
Thanks in advance.
