Warm Air Gas Heating Replacement

wallbash

Another huge fan of J & S warm air heating.
My system has been very reliable , the service engineer's father originally installed the boiler when the house was built.Is it efficient ? don't know . I have nothing to compare it with . But the heating bills are manageable. Also with grown up family , 24 hour hot water is a god send.

Have an old Lincoln warm air heater circa 1973 running with an old conventional gas boiler for hot water.
Both very simple and both use pilot lights but I think there must be vastly more efficient replacements available.
J&S are the only replacements I have found in the UK - but please let me know otherwise.
Just returned from checking out a friend's system in Canada. The property was sizeable but the Carrier "forced air furnace" in the basement was only about 500mm x 500mm x 1200mm plus bolted on humidifier and ac.
The air inlet and flue outlet were both plastic pipes of about 70mm dia. I was told that the efficiency was around 93% and the modern ones are now 96%. Water was heated by a seperate furnace. No pilot lights.
Are there any installers of Carrier or similar units in the UK ?
Thanks in anticipation.

my 3 year old J&S warm air uses a pilot light. I would be amazed if it uses as much as you say. I never switch it off and now you have me thinking...

[/QUOTE]and has anyone recently replaced their old warm air heating with new modern warm air heating? and did they use less gas?[/QUOTE]

I use much the same as before when I had an old J&S

[/QUOTE]in my last house I had an open coal fire to heat the house and supply hot water, an immersion in the summer and electric fires and oil filled radiators all over the place and no gas or central heating.

I have a wall mounted gas multi point to supply instant unlimited hot water.
I paid about £400 to buy and have it fitted. It serves me well except if I am using the mixer tap upstairs and someone for instance pulls the flush downstairs or runs a tap, then my water temperature changes as the flow decreases :eek: I think it would be the same for a shower.

I have J&S warm air heating and my gas usage for the pilot light for hot water is 3 kWh a day and for the heating is 6 kWh a day.

We use 20,017 kWh of gas a year. That was what we used from March 2010 to March 2011 according to eon.

Had to do without hot water for a day so OH could work it out and then without heating for a day to work out the heating usage, but at least he did that when it was warm.

In the summer when we just use the gas for hot water and cooking we normally use 18kWh a day, just now it is 24 kWh a day because the pilot light for the heating is still on, just in case we need to put the heating on.

OH reads the meter every day at the same time and enters it in his spreadsheet. The joys of being retired.

I read several posts here by people who might have to replace their old johnson starley units. Check out the Lennox units from USA they are imported into UK by Gasflow in Northampton, they also allow cooling in summer and as the furnace is a condensing unit they are about twice as efficient as the open flued J&S units. Also they have no pilot light in answer to one of the posts. These also allow an external heat pump to be used which means you don't even use any gas at all as it uses heat from the air outside to heat your house until the outside air gets below 7 deg C then it uses gas. (uses about 2kW electricity to get 10.5 kW of heat into the house that's 500% efficient !) I had a Lennox unit when I lived in USA and it was excellent. I am in the process of doing exactly this replacement in a property in East Sussex.

I cant post a proper link so build it from the above.
No, I do not work for any of these companies
