Underfloor heating

In answer to your question as to how the boiler needs to run it is best for reliability and efficiency to use a thermal store to supply the ufh. The ufh needs to run at a lower temp / different times than the rads and can be supplied by the thermal store which is heated when the boiler is running the rads, thereby reducing boiler cycles.
You also have the option to heat an immersion coil in the store with pv at a later stage of any heat source available.
Check buildhub or navitron forums for advice on design detail.

I know other say you must run these systems 24/7 we found the house was getting to hot upstairs.
we only have underfloor downstairs and rads upstairs, but the upstairs system , controlled seperately virtually never runs.
i put a time clock on the underfloor cutting out about 9pm and cutting back in half hour before rising.
must say I love the underfloor, especially as I never wear shoes inside :)

It works in a very different way to radiators as has probably already been said, you’re right in that you do leave it on at a pre set temp, the zone valves control each area differently. it’s not much good if you come home and are cold as it’ll take to long to warm up. Was toying with putting it in an similar size extension to what you have but not economical unless I install a second boiler as the remainder of the house is radiators. Great way of doing it if you’re starting from scratch with plenty of insulation.
No need for a separate boiler

I was thinking if that was the way to go to heat a buffer tank of water and then it can draw off that's until it needs heated up again. Should of gone for a pv system when the fit were on...anyway...hindsight and all that. The only other option in the winter we have a small stream that runs a fair bit of water and a drop height of maybe 4/5m wonder if that run through a small turbine would heat up anything in a tank of water. Or go the easier option just buy oil

Just recently renovated whole property, radiators pipes all out, installed hot water UFH throughout.
To early to know running costs but a heads up to what's available, looked at several systems then found these people, whole property (185m2) installed in 3 days.
No digging, No dust, no water, no moving skirting or doors, brilliant.

Wont it just lose heat into the ground as you’ve no insulation underneath?

If your oil boiler is young/efficient/sufficient capacity to cope with the extra load then I suspect its the economic solution and still run it with a decent size thermal store for the ufh.

Motivation in farming is a challenging subject to tackle.
