Instantaneous water heaters
These water heaters are either electric or gas. They are reduced-pressure systems. This is because the flow of water from the main supply is reduced and this allows the instantaneous heating of the water as it passes through the water heater.
These water heating systems can be installed either inside or outside a house. However gas water heaters are mainly installed outside. This is because gas water heaters installed inside need to have a flue pipe from the heater to the outside of the building for ventilation of burner exhaust gases. This costs money, so it is cheaper to put the water heater outside. It is also less obtrusive on a side wall than inside the home.
Gas instantaneous water heaters should be serviced regularly – say at least every two years. The costs of servicing gas instantaneous hot water systems needs to be taken into account when working out which system will be the cheapest to buy and run. Electric instantaneous water heaters normally do not require maintenance.
Electrical and standard gas instantaneous water heaters have a reduced flow of water and they can normally supply only one tap with hot water at any one time. These systems are not recommended for large homes. There is little point in having a home with three bathrooms if you can only use one bathroom at a time. However, for single bathroom homes or where an irregular supply of hot water is needed (such as for occasional showers by members of your sports teams) instantaneous water heaters can provide a never-ending supply of hot water.
