The above is how to waste gas and lose control of the system in my opinion.
1, Just fit low temperature radiators to all zones other that the area heated by the underfloor heating. these run on the same water temperature as the underfloor heating ( golden rule, boiler never works outside condensing mode)
2, Fit a New Glowworm Energy system boiler with a systempro3 controller plus outside weather compensation module, then control the three floors with a climbapro2 programmable thermostat. ( golden rule, never leave a room without heat, it will suck the heat from the rooms next to it)
3, Turn the heating on in October and off in May, set the thermostats to lower the room temperatures by 3 or 4 degrees at night.
4, Fit a hot water storage vessel that will accept a tubular file type thermistor so that the boiler can heat the stored hot water to 60 degrees.
Benefits, heatings on all the time ; only the heat required is put into the system from 20 degrees up to say 48 degrees ; you don't get overheated floors/rooms above as stratification will not happen ; you will be very comfortable ; your gas bill will be less that the system above ; you only need a boiler KW rated to the maximum load either the hot water tank or the heating load. Hot water is priority with this system.
Tip, use liquid floor screed maximum 45mm deep, (fast heat up)
No i don't work for Glowworm, YES i have been in this heating/gas game a long time, Yes i have this system ( earlier boiler but the new one is better). In my opinion nobody can compete with Glowworms complete weather compensated package systems. i have fitted them for seven years.
Got an old style, thick walled 3 bedroom terrace - door to hallway, living room off to left, backroom next, kitchen at end of hall. Upstairs got big front bedroom (above front room) smaller room above back room, small room 2 above kitchen, what sort of price would I be looking at to get a smart system with what you say fitted ? Radiators in hallway (2, 1 big 1 small), front room, back room, kitchen, all 3 bedrooms. We have a loft but it's for storage, also no proper insulation. Don't wanna put in under floor heating, just the boiler and the other bits you said
so your looking at £800 just to install thermostats ... lol that's nearly the cost of a complete central heating system in a small house ??? what a waste of money it would take what 8 yrs or so to recoup the cost .. why not just fit thermo's to each rad at £8 a piece ...
or even put a jumper on way to much for way to little ..
What does it matter now if men believe or no?

For a digital home, maybe. That begs the question, do we want a digital home?
If that's what rocks your boat. Why on earth do I want to control my home's heating from afar? I simply put it into 'away' mode, and it sets a guard temperature. While I'm home, decent thermostatic valves and an overall programmable thermostat does the job perfectly well. And £800 for thermostats? No. Just .... no. Absolutely not.
I'm interested in a digital home only in so far as it works for me. And that .... doesn't.
Well I use the Honeywell Total Connect Comfort. Zone control over the whole house from anywhere in the world. My bills have plummeted.
We had to replace our boiler in Feb and at the same time decided to replace the themostat as the one we had never kept the right time (was supposed to auto set and had no controls for override but it never showed the right time). After looking at several options we went for the Nest for the following reasons:
1) Due to the house being old the wall construction meant that wiring a themostat to the boiler was not good option
2) The house isnt split into zones on the central heating its whole house or nothing (so no point in multi themostat set ups)
3) The money no object system was a Honeywell one that had individual wireless radiator values that were controlled by a central box but this was far far too expensive
4) Had an offer on the Nest so that it was just less than £150
I think it has worked well for our needs although it took a bit of time to get the program right (cause it turns itself on early to get the house to temp at the time you set not turn on at the time you set) but i do like the fact that it learns certain things so can turn off the heating early and let the latent heat in the rads get it to temp so you dont overrun the target temp.
No real opinion on the product itself, but having a product (or is it company?) name of Heatmiser automatically gives it a plus in my book...
Solid wall construction and if sash windows forget it, heat loss to high. the cost of low water temp rads is over three times a normal rad, say nine rads £2500. to £3000. just for rads, boiler £1200. control package £500, pipe work £300. + labour, all in maybe £6 or 7000. your heat loss would make the system work hard all the time and at -5 deg would not cope. you need almost 2010 building regs home to meet u values.
