Yes, you have a non condensing welded tube boiler in the base, plus an economiser (secondary heat exchanger) in the area above. There is a lot of water in the two boilers, and the pump is sensibly located between the two to minimise turbulance etc.
The boiler is designed to act as a buffer between demand and burner.
It is not a modern product, being designed between 1959-1982, but the engineering principles were sound, and remain valid. Mr A Kidd managed to design the UK's first condensing boiler right first time.
Many modern boiler manufacturers with huge budgets and design teams have failed where he triumphed years before.
He demonstrated his Model 2 oil running (without a flue) in 1982 at the IEE London, to much acclaim.
Clearly representatives from some of the UK boiler industry weren't in the audience, because they were still designing rubbish 20 years later.
He triumphed with a large boiler, not a small wall hung model.
Is the pump a shunt pump or a pump for CH & DHW? I once fitted a DHW plate heat exchanger on a 60kW oil boiler that had a decent water content in the heat exchanger. It was an exterior model so well insulated but fitted indoors; got it cheap. The Kidd sound like it but gas. I arranged for it keep the boiler heat exchanger hot and when DHW called it operated like a combi. The flow rate from a 60kW boiler was superb and the integral water store in the boiler heat exchanger worked well indeed.
I have a job where using this way using an Archie Kidd (50-55 KW?) would save a lot of cost and space as no cylinder would be required. I need to know how the Kidd works. The Kidd must operate on gravity as it has a number of tappings. Does it have a fanned flue? It would be the price of the boiler, maybe a pump, flow switch and plate heat exchanger.
Obviously I would need to price up the Kidd boiler approx 50 KW upwards. Although an expensive boiler, savings on cylinders and valves would offset that.
If I had to go for U16 gas meter, what is the cost of having a meter this large?
