Questions you need to ask when buying a new hot water system
HOW MUCH HOT WATER DO YOU NEED CURRENTLY?
This largely depends on how many people are in the household and how many use hot water during peak and off-peak hours. You also need to identify how many outlets or bathrooms are needed to be supplied with hot water.
WHAT IS YOUR EXISTING HOT WATER HEATER?
If you are looking for a hot water replacement, this is an important question to ask yourself. You spend less on the installation if the necessary setup is already in place.
Hot water heaters can be classified into two types: the traditional storage hot water systems and the tankless or hot water systems, otherwise known as continuous flow water heaters or instant hot water systems.
WHAT ARE THE AVAILABLE UTILTIES IN YOUR AREA?
Do you have mains gas connection? If not, you can get LPG or propane fuelled gas hot water systems or the electric models . Natural gas fuelled water heaters are certainly not options for you if your area could not provide mains gas connections.
Do YOU HAVE SERVICING CLEARANCE FOR YOUR HOT WATER HEATER?
If you are inclined to go for a gas storage hot water heater, please take note that you will need to have a servicing clearance of at least 61cm in front, and 5.1 cm on each side. If you are going to install your gas water heater inside, you need to have a flue installed for ventilation purposes.
