Making sure your tankless water heater is properly installed and maintained will optimize its energy efficiency, especially since water heaters are one of the many appliances we rely on every day. Whether gas or electric, they are generally very dependable and quiet. A tankless water heater can last for a decade or more, and save you money as long as proper annual maintenance is performed.
Proper installation of your tankless water heater depends on many factors, so it is important to have a qualified and licensed plumbing and heating contractor install your tankless water heater. Before selecting a contractor request estimates in writing, obtain references, check the company with your local Better Business Bureau, and make sure they have a proper permit.
Tankless water heaters are now designed to last 20- 30 years. This is done by owning a high quality water heater, and by preforming a little maintenance on it. Without maintaining your tankless water heater investment you might only get half that time.
Water qualities are different all over the country, and even good water has minerals in it that over time will build up on the interior walls of the tanks heating chambers. The industry standard recommendations are once per year turn the tankless water heater off, and flush out with white vinegar and water using a submersible water pump to remove the calcium deposit buildup. You can find submersible water pumps at most home improvement and hardware stores.
The steps to take to perform your annual tankless water heater maintenance are:
- Turn off the water heater.
- Turn off the incoming and outgoing water valves.
- Fill a bucket with a gallon of white vinegar.
- Connect a short length garden hose to the outgoing water valve.
- Place the tub of vinegar under the hose and valves, and then connect a garden hose to the incoming water valve.
- Connect the other end of the hose to a water pump.
- Place the submersible water pump into the tub of vinegar.
- Open the outgoing and incoming water valves, and turn the water pump on. Allow the tank to flush for 15 to 30 minutes. After you are done flushing vinegar through the tank, flush some clean water through it for a few minutes to make sure all of the vinegar is out.
Summer means barbecues, family gatherings, evenings with friends on the patio, and a cool home to step inside to cool down. Did you know that using an evaporated cooling system will ensure your home is cooled effectively for a fraction of the cost of a refrigerated system? If you have not checked your air conditioning unit here’s how to get your air conditioner ready for summer.
- Check The Fan Belts On The Condenser and The Fan: These can easily be replaced, just do not tighten too much otherwise you can damage the shaft bearings.
- Replace or Clean the Filter at Least Once a Month: This is very important since the filter is what catches dust, pollens and other allergens, preventing them from entering your house. If the filter is clogged with dust and pet hair, it slows down the cold airflow, making the system run harder and longer costing you more money in the long run.
- Clean the Coils: You can obtain a commercial coil cleaner at any hardware store that you apply with a sprayer, following the manufacturer’s directions.
- Oil the Bearings: Put five to ten drops of light machine oil in each hole and rotate the shaft three or four times to make sure it is distributed properly.
- Examine the Condenser: Make sure the condenser is clear of leaves, debris, and vegetation, otherwise the air flow will be restricted.
- Insulate the Cool Line: This runs from the condenser to the compressor. Make sure it is insulated with snap on urethane or other high R-value insulation.
- Check the Temperature: Use two thermometers at the same time to measure the warm return air entering the evaporator coil and the coil discharge air entering the house. The difference between the two measurements should be at least 12F to 16F or greater. If a lower temperature difference is indicated, you should have the refrigerant checked by an HVAC professional.
Other steps to take in order to reduce your energy bill are to keep the windows closed in hot weather with the blinds tilted to block direct sunlight. Turn up your house thermostat as high as you comfortably can and open your windows at night to allow the cooler air to circulate in the house.
