right guys I've been wfp for 8 years now and I'm thinking of getting the hot system in for winter. first of all help needed in what kit is needed what boiler do you all tend to favour? what litre per minute is sufficient? do i need to get thermal hose? can the pump take hot water running through it? what is the system lay out like, e.g boiler after pump I'm assuming. do they use much gas? any problems working with this system in the winter period? thank you in advance.
