So far, we’ve worked out whether we need a tankless or tanked hot water system, and we’ve worked out what kind of power source we need. For those of you who think a tankless water heater is better suited to your needs, the next thing you need to work out is where to put it.
With an outdoor tankless hot water heater, your main concern is vandalism. Outdoor instant heaters allow you to safeguard against the chance of a leak. Should a leak occur in an outdoor water heater, there is no potential for damage to your home.
The other main benefit of an outdoor fitting is specific to tankless gas water heaters; you do not need to worry about ventilation. Gas water heaters need a supply of air and a ventilation system to function. Locating the heating system outside negates the need for any exhaust pipes to be installed in your home.
For those of you who live in an area that is subject to extremes of temperature, some insulation on your water pipes is highly recommended to prevent freezing.
Indoor tankless hot water heaters are generally more commonly found with electrical heaters. With an indoor heater, you don’t need to be concerned about freezing exposed pipes or vandalism. There are, however, some drawbacks. With a gas powered indoor heater, you will need to ensure that the ventilation exhaust is correctly installed.
This usually means less choice as to the location of your heater. As well as this, with an outdoor gas heater you do not need to be as concerned of the consequences of a gas leak. Although highly unlikely to ever occur, some people prefer the security of knowing they are not at risk.
