    Hi ​@Sallyab 

     

    Thanks for posting your question on here because it is one we get from time to time and one we can’t really answer. The reason is there are so many factors that are individual to you regarding not only your property but also your lifestyle.

     

    My recommendation is to always invite a qualified heating engineer to assess your property and what you want out of the heating and hot water as well. Search for: Home Energy Survey

     

    Now, a survey may cost you money but a good heating engineer will save you more than you pay for a survey. The survey cost (if there is one) is once but the money saved (or possibly lost by making a decision without advice) is every month. You also need to consider what tariff is best for what ever decision you go with.

     

    There are also some blogs on here from people who have had an ASHP installed and I’ll give a shout out to ​@BPLightlog who produced an excellent blog on the subject from personal experience. Reading it will give you familiarity with  the term used and how the process works.

     

     

    If you wish please come back on here with any further questions you may have, possibly arising from a survey or two or after reading the blog. We have volunteers on here who have different experiences of heat pumps (I have an Air to Air heat pump) and their combined knowledge and wisdom is awesome and free of charge.

    Hi ​@Sallyab and a warm welcome to the OVO Forum community 😁. I hope you had a good weekend.

     

    @Peter E’s advice here is spot on - getting the advice of an expert here is the best way to go. If they do advise that a heat pump is the best way to go then this community is a treasure trove of info. 

     

    I’d recommend checking if you’re eligible for the Boiler Upgrade Scheme, which could result in a large grant for replacing your fossil fuel system. If you’re advised to go for a heat pump by an expert then you’d be able to book the installation through OVO if you’d like.

     

    If you do a Google search of ‘energy advice in (your local area)’ you might find that your council offers free, impartial advice, alongside other charities and organisations that could help.

     

    Let us know how you get on - we’ll help however we can.
