Heat Pump Pool Heaters Buying Guide
You might have noted there are types and models of heat pump pool heaters. That makes it critical to know what to look for when choosing your unit.
These features include:
- Efficient Product: It is easy to consider the buying price of a product, but the efficiency also matters. An efficient unit reduces operating costs, making it more affordable in the long-run.

It is ideal to pick a pump that gives you daily, monthly, and lifetime heating costs.
- Heat Exchanger: It is a tool that transfers heat from the condenser to the water. Some units use Cupro-nickel or copper exchangers because they are more affordable and transfer heat efficiently.

Modern models come with titanium exchangers since they are corrosion-free and more durable.
- Compressor: It helps the heat pump to condense refrigerant into warm gases for heating the water. You can find a model with either a reciprocating or scroll compressor.
Reciprocating ones are small and more affordable but inefficient. The other model uses metal scrolls to compress the air as opposed to pistons, making it more efficient.
- Costs: As noted, the buying price of a heating machine is not as vital as the operating one. Other costs you should consider are the installation ones and efficiency.
You also need to consider the maintenance cost and repair.
- Warranty: It can come in handy to reduce your repair costs and ensure you save bucks when the model stops working. The best brand should provide a long term warranty to cover parts and labor.
