Vaillant Boiler Replacement & Upgrades
Vaillant ecoTEC condensing boilers — installation, repair, maintenance, parts and emergency service for one of Europe’s oldest heating names.
Repair or Replace? Real Numbers, Honest Advice
Replacing an older European boiler — or an aging ecoTEC — with a current ecoTEC plus keeps the system philosophy intact while updating efficiency and controls. We confirm parts-availability realities with you before committing, so the ownership experience matches the engineering.
Our rule of thumb across brands: if the unit is 15+ years old and the repair quote passes $600–$800, price a replacement before you commit — efficiency savings of 15–20% often recover the cost faster than another round of aging-unit repairs. We quote both paths so you decide with real numbers, and we handle rebate paperwork on qualifying high-efficiency installs.

- ✓ Removal and responsible disposal of the old unit

Vaillant FAQs
What does Vaillant F.28 mean?
F.28 is an ignition failure — the boiler attempted to light and locked out. Causes range from gas-supply issues and worn ignition electrodes to a faulty gas valve. One reset is reasonable; repeated F.28 lockouts need diagnosis, not repeated resets.
Can you get Vaillant parts in Canada?
Yes, with realistic expectations: common service parts are available through Canadian distribution, while some control components carry lead times. We confirm availability during diagnosis and quote repair timelines honestly before you commit.
What does Vaillant F.22 mean?
F.22 is low system water pressure. Repressurize to about 1.2–1.5 bar via the filling loop; if pressure keeps dropping, there is a leak or an expansion-vessel problem that needs professional attention rather than constant topping up.
