Boiler Repair Calgary — Hydronic Heating Experts
Hydronic and radiant heating need specialists who understand boilers. R N T Plumbing and Heating repairs and services boilers across Calgary — fast diagnostics, all brands, honest pricing.
What to Expect
Boilers and radiant heating systems deliver some of the most comfortable, even heat available — but they need technicians who truly understand hydronics. R N T Plumbing and Heating specializes in boiler repair and service across Calgary.
We diagnose pressure issues, leaks, air locks, and circulator problems accurately, and service all major boiler brands. Whether you have radiant floor heating, baseboard radiators, or a combination system, we'll get your heat back reliably.
Hydronic systems run at lower temperatures and deliver even, draft-free heat, but they require technicians who understand water chemistry, pressure, and zone controls. Our team is trained specifically on boilers and radiant systems, so we diagnose problems other contractors miss — like air-locked loops or unbalanced manifolds.
We service both conventional cast-iron boilers and modern high-efficiency condensing models, and we'll always give you an honest repair-versus-replace comparison. If a repair makes sense, we do it well; if replacement is the better value, we'll explain why with clear pricing.

"I manage several properties in Calgary. I have used several different plumbing companies over the years and by far R N T Plumbing has been the best Most recently another company came in because 3 out of 4 sinks had no water. They said all 3 faucets had to be replaced. I decided to get a second opinion from R N T and sure enough no need for replacement, just a part. Saved me over $2000. Such a great team, friendly, very responsive and they want to help, not just make money. Thank you R N T."

"If you need a plumber, look no further than R N T plumbing and Heating. Rob provided absolute top-tier service. He was honest about what actually needed to be fixed, didn't try to upsell me on unnecessary parts, and he was incredibly respectful of my home.

"Bobby showed up on time and inspected my hot water heater. I thought I was going to need a replacement that was going to cost me thousands of dollars, and he ended up saving that for me! He also installed a set of shower taps and had to run some new lines. He was professional and courteous and when I need his help again, I know he will be there, on time, professional and clean up after himself."
