s plan/y plan heating systems.

Hi guys. Ive had a look at my central heating system and hot water system after moving into our property. im no expert plumber but a competent diy er. I have a grant vortex oil condensing boiler in situ and was fitted approx 1 yr ago. However when i went to the programmer on the wall to call for hot water only it doesnt work. if I call for central heating the hot water heats fine in the hot water storage tank in the airing cupboard. Ive done a bit of research and looked at S plan heating systems. On investigation of my own system i have no cylinder thermostat or motorised valves fitted in the hot water storage tank. Ive checked the rest of the house and i dont have any motorised valves fitted at all! Ive also checked all rooms in the house and there are no wall thermostats or TRV on any of the rads. I guess this system was never installed properly. I was thinking of having a go at this myself to correct the problem. Im looking to call for hot water and central heating independently. Is it just a matter of trying to adopt to an S plan system and install motorised valves and fit a cylinder thermostat or is it more complicated than that. Ive a friend who is an electrician who could do the electrical work for me. Ive a back boiler fitted and was wondering would this complicate matters. Thanks in advance Jim.

sounds like a gravity hot water sysyem!
you should however be able to get hot water on its own with this system,just not heating!

You've quite probably an oil to solid fuel link up. Unless you've a manual valve in your hotpress to shut of the heating during the summer months you're looking at bringing new pipework in from the boiler

Thanks for the response guys. It sounds a bit more complicated than I thought so I'll get someone in to have a look at it for me.
