A refreshing and relaxing bath in your pool is impossible to beat However, controlling the temperatures that is a result of thousands of litres water can be difficult and costly. There are a variety of methods for heating pools, whether commercial or domestic and whether outdoor or indoor. Solar panels are increasing in global popularity, however they’re likely to remain a choice only for warmer climates, since they’re unable to produce enough heat to keep up with the cooler temperatures that we see within the UK. The heat pumps are a very popular alternative. While initially costly to purchase and install, they are affordable to run since they make use of a tiny amount energy to absorb the heat in the air before transfer it to the water. However, they require quite a while to heat up a pool, and are only suitable for summer use only, as they rely on the higher temperatures of the air.
How does a Heat Pump work:
A fan draws air from outside and focuses it on the radiator of the evaporator coil.
The liquid refrigerant inside the coil absorbs heat of the air and transforms it into gas
The warm gas flows through a compressor which amplifies the temperature
The hot gas that is produced goes through the condenser
The condenser transfer warmth from the gas into the water in the cooler pool that circulates through the heat pump.
This heated pool water gets then returned to the pool.
The hot gas is transformed back to liquid form when it cools rapidly in the condenser coil before moving on to the Evaporator.
This process is repeated over and over to ensure that there is a constant flowing flow of warm water.
Boiler systems are by far the most popular one source of heating for swimming pools across the UK. They are consistently more popular than heat pumps due to the speed with that they can heat pools and also because they don’t rely on the temperature of the air, which means they are able to be used throughout the year. They’re also cheaper to purchase than a heat pump, however their operating costs are more expensive since they require fuel to operate. Boilers generate heat by burning oil or gas in a combustion chamber. the heat is transferred to the water taken out of the pool, before sending it into the water pool.
What is the process by which a gas and oil pool boiler operates:
The cold water is pumped from the pool and flows through the filter.
The oil or gas is ignited in an ignition chamber.
The heat that is generated is transferred through the water.
The warm water is returned to the pool.
This process repeats over and over to ensure a steady continuous flow of water that is warm. The length of time required for gas boilers to heat an outdoor pool will differ according to the dimensions of the pool and the amount of water that is being heated. However, for a standard-sized swimming pool for a household, it generally will take between one to two days bring the water up to a suitable temperature suitable for swimming.
Domestic boiler equipped with heat exchanger
You could also utilize an ordinary domestic boiler to warm your pool. The boiler transmits their heat directly to water in your pool through a specially-designed heat exchanger. While not a recommended method of heating your pool this choice can have many benefits. It includes the advantage of a long domestic boiler warranty as well as the additional flexibility that comes with using it to provide hot water.
How much will a replacement swimming boiler for a pool cost?
Based on the size of your pool the cost of a new oil or gas swimming pool boiler installation can cost approximately £5000.
Like all appliances, making sure your pool boiler is regularly serviced regularly is essential to ensure security, reliability and long-term durability. A regular service is strongly suggested and is a requirement of warranty for certain manufacturers. Repairs and maintenance should be handled by a trained pool boiler technician Of course, however, to avoid issues it’s also a great idea for anyone who owns a pool to do these things regularly:
Clean the filter since the boiler requires a continuous flow of water for it to operate correctly.
Check that the skimmer in the pool is free of obstruction and clean
The tanks should be cleaned to remove any debris and stop the burner’s openings from getting blocked.
Verify that the gas or oil pipework to ensure it isn’t corroded.
If your pool’s boiler is approaching an end point in its lifespan generally after 10 years, another option to consider is to put in another system in conjunction with it and then switch it to be the primary source of heat and keep the previous one in use. In this way, you’ll be able to be sure that you’ll have a backup option that will allow you to continue heating performance in any repair time.
