Trianco and Trianco-Heatmaker are different companies.

Corporate History

Trianco Heating was founded as New Chambers in the 1850s. It was known for its coal fire ranges at Thorncliffe in Sheffield. Eventually the company expanded to produce fireplaces, back boilers, and free-standing heaters. Trianco-Stewart, a small petroleum manufacturer, was merged with New Chambers in the early 1970s, resulting in the modern Trianco Heating Company.

The company is one of the last British heating product manufacturers and in recent years has entered the renewables market, providing a variety of biomass heating products.

Product Lines

Trianco has five major kinds of boilers, each comprised of various models. These five are: Greenstar, Aztec, Eurostar, Contractor and TRG.

Greenflame, a biomass wood pellet boiler available as both an inside and outside unit, features a small footprint and efficiencies of over 90%.

Aztec, which features Classic, Combi and System models, is essentially maintenance-free, gives off no toxic gases, and performs its own diagnostic testing. The Aztec is also solar compatible if placed outdoors.

Eurostar is an oil-fired boiler with combi models designed for indoor and outdoor installation. The Eurostar models are floor mounted with heating outputs from 50,000-240,000 BTUs.

The Contractor provides efficiencies in excess of 86% and features the Ecoflam MAX burner. The Contractor provides low NOx emissions.

The TRG is a floor standing solid fuel boiler that can burn for up to 14 hours with heating outputs of 45,000 to 80,000 BTUs. It is designed to provide heat and hot water to a 2-3 bedroom property.


Trianco’s warranty varies by product line. For example, the TRG boiler has a 12-month parts and labor guarantee, and a 4-year parts guarantee on the heat exchanger, while the Eurostar boiler has a 2-year parts guarantee and a 5-year heat exchanger guarantee.

Trianco Boiler Reviews

"Experience with my city boiler"

5.0 rating
Very Satisfied

I currently rent, so this is my experience with a boiler over the past year (it is only about five years old). It's never needed to be repaired, which is great. I only like this boiler I don't dislike anything about it (although it is noisy when the home is completely quiet, but that's something I don't mind). Our water heats up in under five seconds, and I've never had to take a cold shower the entire time I've been here. DC has had a particularly bad winter this year, so that's been great. I would definitely recommend this brand to a friend or anyone looking for a boiler. It's solid and has done well by our standards.

"Great unit"

5.0 rating
Very Satisfied

I have a 24-year-old Heatmaker II with integral hot water on demand. This has been an extremely reliable and low-cost unit to own. I have made a few repairs (pressure switch, internal coaxial flue pipe and water air bleed vents). All low-cost items. This unit runs very clean and I have only opened the flame pod one time in 24 years! It was very clean inside (15 years). It is now getting tired and probably not as efficient as a new unit. The hot water is endless. 2 showers running and wash at the same time with no loss in temperature. I hope I can find something as reliable. I wish Trianco was still in business.

"Heat Maker II"

5.0 rating
Very Satisfied

85,000 output, 85% efficient, propane. This has been an excellent boiler/ hot water unit. Came with the house 15yrs ago. I estimate that it's ~20 yrs. Regular cleanings and replaced a couple pressure switches and the vent once. Showing its age and techs say parts are getting hrs to find. Considering a new one and very dismayed by all of the negative reviews on every brand. I guess manufacturing pride really is not what it used to be.
