Old furnace, change of repair?

kpunch

Hi, I just bought an old house last year, with an bi-energy heater. It worked through last winter,but it seems not switching correctly between electricity and oil, When it worked with oil it does not stop at temperature, while it works with electricity it takes long time to warm. It cost me a big bill for oil and electricity. I changed the thermostat, but seems makes no difference.



The heater is branded 'Brock', with model number L0-1MQH' and 'QH-1AR5'. I have limited knowledge of heater, can't even tell what year is the furnace made. Is it worth repairing or shall I replace it? Any advise is welcome.

Familiarity:

I never in my life heard of one. I thought it might be made by Bock. I found it on the Internets. Maybe a phone call to the number listed on that link would give you what you need.

Many Americans are unaware that there is a vast world on the other side of our borders. Like Canada, where it is far colder than the USA. They like to be warm too. Many Canadian Manufacturers do not want to deal with the USA BS of UL Listing. They have their CSA which seems to be slowly supplanting UL as a testing Standard. In many ways, they are way ahead of the USA and the Wall Street Crime Syndicate and their Bankster Subsidiary.

Thank you for your advice.

From your experience, do you think the problem I described is major or costly to fix?

Quandry:

It sounds like a service issue, not a replacement issue. Best determined by a qualified heating professional with his eye upon it.
