Does anyone have any experience of this product ?

http://www.rayburn-web.co.uk/products/rayburn-oil-series/heatranger-308k

It seems to be the only model that requires no electricity supply, a decided advantage.
Has anyone got one ? are you pleased with it ?
Or know of an alternative that needs no electricity.

I know of someone who is considering one for a planned new house. A fairly large but very well insulated home. Most oil or solid fuel appliances would have a greater output than needed, but one of these sounds ideal.

I have no connection with Rayburn.

They are similar to the other vapourising stoves, except where some have thermostats fitted, that have an electric supply. Even then, it is possible to run them in high or low mode. I would have one except they need about 20 to 40 litres of oil a week, and they do not like being started and stopped. They need al least an annual service which is straightforward and can be done by anyone with practical skills, otherwise you need someone to do it. They act as a space heater, keeping the kitchen comfortable except in the summer when it can be stifling.
Anything further you could ask on http://www.agacentral.com/phpBB3/viewforum.php?f=2

Thanks, the intention is to run it 24/7 in the winter and to leave it turned off in the summer.
Cooking on either the Rayburn or a modern cooker, LPG or electric yet to be decided.
Mains electricity is available, but an appliance that is not reliant on this utility is preferred.
The intention is to heat domestic hot water with the Rayburn in the winter, and from solar thermal in the summer.

That is a good approach. All the cooking can be done in the Rayburn when it’s on, and it’s always ready and waiting. The alternative cooker will only be needed when the Rayburn is off.

So is the oil gravity fed?

I presume it must be gravity fed, without an electric pump I cant see how else it could work.

In the proposed installation an oil elevated oil tank looks easy to achieve.

"back of the fag packet calculations" suggest a heating demand in winter of a few KW. Too much for electricity or LPG to be economic, but not enough to justify central heating.
A solid fuel room heater is proposed in addition, but partly for redundancy in case of oil shortage or breakdown of the Rayburn.

INITIAL proposals

Oil Rayburn for winter cooking and hot water.
Solid fuel stove for extra heat in extreme weather, and as a standby facility.
Summer cooking, electric or LPG.
Summer hot water, solar thermal.
Standby hot water, immersion heater.
Lighting and small appliances, grid electricity.
Small battery charging PV system, primarily for backup.
Large grid tied PV system.
The proposed house is to be of unusually substantial construction so as to resist truly extreme weather, and also have vast thermal mass.


The owners are not hard core doomers, but do wish to be prepared for an uncertain future.

They are friends of the owners of the house discussed here.
