Indirect Fired

An indirect fired water heater is another solution to consider for supplying hot water for your home.

The water is heated by a separate heating source such as a boiler or an existing furnace. The heated water is made from the heat source of the furnace then stored in an insulated tank that circulates the hot water until needed. The water is not heated directly but uses a main boiler to heat up the liquid and circulates it through the heat exchanger installed in the storage tank. Due to the installation of an additional storage tank they allow the main heat source to turn off and thus work efficiently throughout the year. Water can be heated in these systems through using gas, oil, propane, electric, solar energy or a combination of any or all of these.

An indirect fired water heater has a longer life expectancy when compared to a water heater and has excellent recovery rates. It is more efficient than a conventional water heater and is maintenance free.

Do you need a new water heater? Why not consider a tankless water heater?

There are several advantages with tankless water heaters in comparison to the more traditional water heater.

Firstly, a tankless water heater uses less space. It does not need to store water as the water is heated at the point where you require hot water. This means a tankless system is more efficient, has a longer warrantee and a longer life expectancy than a tank hot water heater.

A tankless water heater gives an endless supply of hot water for showers throughout the whole house, or at the point of use – for example in a suite.

Selecting the right size unit is the one of keys to making sure the tankless water heater will perform to your satisfaction and provide the supply and temperature of hot water that you desire. This decision will be based on a number of factors such as how many bathrooms you have, the size of your family, how many showers or baths are taken, your laundry needs, all of these matter because you want to make sure that once you turn that hot water faucet on the hot water never stops until you turn that faucet off.

Sheehan Plumbing can advise you which is the best size of tankless water heater that you need for your residential or commercial space. We can supply, install and service all brands of tankless water heating systems and guarantee your water heating system will be efficient and cost effective.

One of the most popular brands is the Navien Tankless Water Heater.

The Navien tankless averages, more than $160 per year in savings over conventional tank type gas water heaters and $40 per year over conventional tankless gas water heaters.

Since the Navien tankless water heater is only about the size of a carry on suitcase you can free up some valuable living space in your home. Old tank style water heaters take up about 16 sq feet of floor space, since the Navien can be installed on virtually any wall in your home it not only frees up this floor space but it's small size allows for almost limitless installation possibilities allowing the unit to be strategically located for maximum performance and energy efficiency.

Navien Tankless Water Heaters
How Tankless Water Heaters Work
  1. The second a hot water faucet is turned on, the unit is activated.
  2. Flow sensors inside the heater detect the water flow and the computer automatically ignites the burner.
  3. Water circulates through the heat exchanger and the heat exchanger heats the water to the desired temperature.
  4. Naviens two microprocessors continue to control the burners for ideal combustion and steady hot water temperature.
  5. Once the hot water faucet is turned off the unit shuts down until the next time hot water is needed.

Navien's ultra efficient burner system uses less gas resulting in substantial CO2 emission reductions. Less CO2 means less acid rain and less green house gases minimizing ozone layer depletion. By replacing your old water heater with a Navien Tankless you can reduce carbon emissions by approximately 550 lbs per year the equivalent work of 17 trees.
