There are two types of water heater to choose from which you can use in your home and these are the tankless water heater which uses natural gas or propane to operate, and the tank type water heater that operates on electric power or gas. iF you have a tankless water heater you save on energy because the water only gets heated once you turn on your faucet. Since the tank type water heater needs to keep 40 to 50 gallons of water hot inside the tank, then it uses more energy. Although both tankless and tanked water heater give the home a continuous supply of hot water, the tankless requires using only a faucet at a time. This means that the tankless water heater cannot handle the demand if you are using more than one faucet or water outlet, unlike the tank types where you can stock gallons of available hot water which are ready to be dispensed.
When it comes to size, the tankless water heater is very compact which the tank types are vary large. High powered burners are present inside compact water heaters so that it can produce immediate hot water supply and in order to keep it cooler than usual they also have special venting requirements installed. Proper sealing is important so that heat is not spread to another surface. With natural gas being the main power for these tankless water heaters, they need a larger diameter gas pipe which add to the initial installation cost.
Furthermore, your concern with initial cost is to make sure that your bottom line cost in pricing should include installation cost and not just the unit itself. The complexity of estimating your daily volume, water pressure and others requires that you seek help from a professional with skills on this.
If you are going to install your water heater, you need to have the job done right for the first time, and for this you will be needing the services of a professional plumber who will be the installer. With professionals, you are given expert advice on the best water heater to buy for your house, and you will be given a right over all budget for everything. Installation cost is definitely included in this budget.
These water heater systems are combustibles that can burn down your house easily and so safety standards must be followed in their installation. Make sure that the water heated that you buy meets the safety standards outlines by your local government.
