High Efficiency Boiler Installation
Upgrade to a modern condensing boiler for radiant floor heating, baseboard radiators, or hydronic systems. Maximum comfort with minimum energy waste.
Is This Right for You?
Here are the most common situations where homeowners choose this system.
Replacing an old standard boiler
Old boilers waste 15-25% of energy. A modern condensing boiler captures that waste heat, dramatically lowering gas bills.
Homes with radiant floor heating
Condensing boilers are ideal for low-temperature radiant systems, providing even heat distribution across your floors.
Hydronic baseboard or radiator systems
Keep your existing hydronic distribution while upgrading the heat source to a dramatically more efficient boiler.
Combi boiler for heating + hot water
Eliminate your separate water heater with a combi boiler that provides both space heating and on-demand domestic hot water.
Key Benefits
95%+ AFUE Efficiency
Condensing boilers extract maximum heat from combustion gases, wasting almost nothing.
Even, Radiant Heat
Hydronic heating provides the most comfortable, even heat distribution — no cold spots or drafts.
Combi Option
Combi boilers provide space heating and unlimited on-demand hot water from a single compact unit.
Compact Design
Wall-mounted boilers free up valuable floor space compared to bulky old boiler systems.
Licensed & Permitted
All boiler installations include TSBC gas permits, safety inspections, and warranty registration.
Quiet Operation
Modern boilers with modulating burners operate nearly silently compared to older cast-iron units.
How Condensing Boilers Compare
| Feature | Condensing Boiler | Standard Boiler | Gas Furnace | Electric Boiler |
|---|---|---|---|---|
| Efficiency | 95-98% | 80-85% | 96% (AFUE) | 99% |
| Radiant/Hydronic Compatible | ✅ Yes | ✅ Yes | ❌ No | ✅ Yes |
| Operating Cost | ⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐ | ⭐⭐ |
| Combi (Heat + DHW) | ✅ Available | ❌ Separate | ❌ Separate | ✅ Available |
| Size / Footprint | Wall-mount | Floor standing | Floor standing | Wall-mount |
| Noise Level | Very quiet | Moderate | Quiet (variable) | Silent |
Installation Process
Every install follows a rigorous process. Here's a typical walkthrough.
Step 1 — Boiler placement & initial gas/water connections in crawlspace
Step 2 — Copper piping, expansion tank & zone valve connections
Step 3 — Zone manifold, circulation pump & control wiring
Step 4 — Fill, purge, combustion analysis & commissioning
