Tank-Style Water Heater Prices

Conventional, tank water heaters are the most common type of hot water heaters found in homes. They use electricity or natural gas, and store the hot water inside a tank that ranges in size, based on the needs of your home. In residential applications, 40-60 gallon tanks are the common size installed. Due to their large size, most homes have just one storage tank water heater installed, usually in a utility closet, basement, garage or other utility room inside or outside the home.

The easiest projects are those in a garage, indoor or outside utility closet, at ground level with very few obstacles in the way of the water heater itself. Other locations such as attics, basements, crawl spaces under homes, and cluttered utility rooms can add to the time it takes to complete the project, thus the installation cost will rise accordingly.

Tankless Water Heater Costs

On demand, tankless hot water heaters have quickly become the preferred choice by homeowners. Not only do they offer higher efficiency than conventional tank-style water heaters, they take up much less space inside the home and when properly sized, you’ll never run out of hot water in the middle of a shower again! Tankless systems use electricity or natural gas (or propane) to heat the water before it is delivered to your shower, sink, faucet, etc.

Average Tankless Cost by Size

When you install a tankless water heater, you need to be sure to get the right size unit for the number of sinks and showers that will be drawing hot water from it. This is rated in gallons-per-minute, and you’ll need to add up the needs of your home, factor in your lifestyle needs (more than one person showering at the same time, dishwasher running, sink, etc) and adjust the GPM needed for your home. A plumber will walk through this with you during the initial visit and help you decide which size tankless water heater to install in your home. Click here for installation price quotes from qualified plumbers in your area.

Water Usage

• 1-2 gmp / Average Bathroom Sink Faucet
• 3-5 gpm / Kitchen Sink Faucet
• 1-3 gpm / Washing Machine
• 1-3 gpm / Dishwasher
• 1-3 gpm / Single Shower

Using the values above, determine how many will NEED to run at one time and figure out how many gallons per minute your new tankless water heater needs to support. In some cases, a single whole house tankless system is not enough, and you may need to two units.

For example: Dishwasher, washing machine and one shower would mean: 3-9 gpm. Average this to 6 gpm to know the approximate size you need. Again, you should consult with a plumber in your area before coming to a firm decision on the size you need.

Repair Costs for Point of Use Water Heaters

Fortunately, after a point of use water heater is installed, they are very low maintenance. Due to the low cost of this type of hot water heater, it almost makes no sense to even repair when they break. Just the cost of calling out a plumber to diagnose the issue may cost you more than a new unit.

That said – there are a few things that could cause your small water heater to stop working.

• Loss of Water Source? – Is your water turned on in the rest of the home, or has the service valve been shut off to the water heater?
• Has the Circuit Breaker Tripped? – Since almost all point of use systems are electric, you should check your circuit panel to be sure the breaker didn’t trip off.
• No Hot Water, Everything Else Working Fine? If water runs through the unit but its no longer hot, the electric heating element may have gone bad. You can get a replacement heating element for under $50, however at this point, it’s worth it to just replace the unit.

Point of Use Water Heater Installation Costs

Installing a point of use water heater may be a DIY project that many homeowners can do themselves. However, you have to be aware that you need two things to complete the installation. A protected electricity circuit (ground fault) and a source of water. Many homes have garbage disposals that are wired to a ground fault circuit already, so a handy homeowner may be able to bridge off the existing wiring to the disposal. If you already have cold water piped to the area, tapping into the water line is as easy as your own handyman skills can take you. Copper piping may need to be cut, tee’d, and then soldered back into place.

In almost all cases, we suggest to talk to a professional plumber before you try to install your own point of use system. You might be surprised how affordable it is to have a pro handle the work, versus having to pay them much more to fix plumbing or electrical errors you make on your own.
