Pool Heater Installation in Ontario
Gas Versus Electric Heat Pump Heaters
Gas pool heaters bring water up to temperature quickly and work well for occasional use, since the burner fires at full output whenever the pump is running and heat is called for. They need a properly sized gas line, adequate combustion air and clearance from windows and structures as required by code.
Electric heat pump pool heaters draw heat from outdoor air instead of burning fuel, and they generally raise temperature more gradually while running for longer stretches. They need a dedicated electrical circuit, adequate airflow around the unit and enough outdoor space to avoid short cycling the refrigeration circuit against its own exhaust air.

Your current heater cannot keep up
An undersized heater struggles to maintain temperature in windy or shaded pools and runs constantly without reaching setpoint, which is often a sizing issue rather than a fault.
Frequent repairs on an aging heater
Once repair parts become harder to source or multiple components are failing around the same time, replacement is often more sensible than repeated repair visits.
Adding a pool to an existing property
New pool installations need a heater matched to pool volume, surface area and how quickly you want the water to warm after a cold stretch.
Switching from gas to electric or back
Homeowners sometimes change heater type because of gas line access, operating pattern, or wanting a unit that runs without an open flame.
Our Installation Process
- 01
We measure surface area
Note sun exposure and wind exposure, and look at available gas line capacity or electrical panel space before recommending a heater size or type.
- 02
Sizing is based on pool volume
Desired temperature rise and how quickly you expect the pool to warm, not just matching the old heater's rated output.
- 03
Gas units get a correctly sized gas line
And bonding; electric units get a dedicated circuit, disconnect and bonding, with plumbing connected to the existing filtration system either way.
- 04
Once connected, the heater is started, checked for correct ignition or refrigeration operation, and run through a cycle to confirm steady temperature rise
Before we hand it over.
What Installation Typically Costs
Heater unit and sizing
Gas and electric heat pump units differ in upfront cost, with heat pumps generally priced higher but operating on a different pattern than gas burners.
Gas line or electrical work
If the existing gas line or electrical panel needs upgrading to support the new heater, that work adds to the overall installation cost beyond the heater itself.
Plumbing and site preparation
Running new plumbing, setting a pad for an electric unit, or relocating equipment for clearance requirements can affect total installation pricing.
Installing a heater that matches your pool's volume and how you actually use it avoids both an undersized unit that never keeps up and an oversized one that costs more upfront than necessary. Correct gas or electrical sizing from the start also prevents problems that would otherwise surface as nuisance faults later.
Clearances and Interlocks We Follow
Pool heater installation must meet clearance requirements from windows, doors, decks and property lines, and the gas line must be sized to deliver full rated BTU input without pressure drop under load. Electric heat pump units require correct bonding, a dedicated circuit and GFCI protection as applicable. The flow interlock that shuts the heater down on low water flow is never bypassed or defeated during commissioning, even briefly, since doing so risks damaging the heat exchanger or creating an unsafe condition at startup.
Why Choose HeatNest for Installation
HeatNest sizes pool heaters to the pool rather than defaulting to a standard model, and handles the gas, plumbing or electrical work needed to connect it properly across Ontario properties.
Proper sizing calculations
We size based on pool volume and desired heat up time, not a generic match to the old unit's rated output.
Gas and electric capability
We install both gas burner and electric heat pump pool heaters, handling the different connections each one requires.
Full commissioning test
Every installation is run through a complete cycle to confirm correct operation before we consider the job finished.
Planning Before Installation Day
A heater sized for occasional evening swims is
A different project than one meant to hold temperature all day, so tell us how you plan to use the pool.
Clearances from structures
Clearances from structures and property lines can limit where a heater is placed, so confirming location before ordering equipment avoids delays.
Warranty coverage on a new pool heater is generally
Conditional on correct installation and maintenance, so keep installation and service records on file.
Pool Heater Installation Questions
+Should I choose a gas or electric heat pump pool heater?
The right choice depends on how you use the pool, your available gas or electrical capacity, and how quickly you want temperature to rise. We can walk through the tradeoffs based on your site and pool.
+How is a pool heater sized for my pool?
Sizing accounts for pool surface area, volume, typical wind and sun exposure, and how fast you want the water to heat, rather than simply matching an existing heater's rated output.
+Will my existing gas line support a new pool heater?
Whether your line will support a new heater depends on the line size and what else is already connected to it. We check capacity during the site assessment and recommend an upgrade if the existing line cannot deliver full rated input.
+Does an electric heat pump pool heater need special electrical work?
Yes. It needs a dedicated circuit sized to the unit, a disconnect and proper bonding. We confirm your panel has capacity before recommending installation.
+Are rebates available for electric pool heaters?
Check current program rules directly with the administrator before including a rebate in your budget. Eligibility may depend on location, equipment and application timing. Pool equipment should not be assumed eligible for incentives advertised for home heating upgrades.
+How long does pool heater installation take?
Timing depends on whether existing gas, electrical or plumbing connections need upgrading. A straightforward swap is faster than a new installation requiring new line runs.
