Electric Swimming Pool Heaters

A quick guide to electric pool heaters. 

Electric pool heaters are divided in to two groups 

Direct Electric Heaters

 using a heating element to warm the water.

Heat Pumps 

powered by electricity but using a refrigerant gas to transfer heat to the water.

In this section we only deal with Direct Electric Heaters for Heat Pumps visit the  Pool Heat Pump section

The electric heaters shown here all have one thing in common, they use a heating element to heat the water. The elements are quite similar to the elements used in a domestic kettle but you cannot put a heater directly in to the pool water, the water must flow over the elements propelled by the swimming pool's circulation pump. So the heater is plumbed in to the the return flow pipe work of the swimming pool, electricity heats up the element, the water flows over the hot element and is heated a tiny amount. This process continues all the while the pump is running and little by little the temperature of the pool rises over the course of a day or two to the desired temperature.

Can I plug it straight in to the mains?  

Yes and no. The mains plug socket on your wall can take a 3kw heater so you can plug in the Elecro Nano or the Intex Heater. Any heater that has a capacity greater than 3kw cannot be plugged in and will need to be wired, by an electrician, to your mains curcuit. 

What is the difference between one heater and another? 

The main difference between heaters is their heating capacity and their build quality. The chinese made Intex heater is a very good heater at a very low price. The UK made Elecro and Thermalec heaters are of a higher build quality.

When the capacity of an electric pool heater exceeds 12kw the heater must be 3 Phase. Single Phase is the typical type of electricity supply to a domestic property, 3 Phase is the kind of supply that factories or farm will have. A domestic property can request a 3 Phase supply. The Elecro Titan Optima is designed to go on to a 3 Phase supply
