hot water heater and servicing by G&S Mechanical:

With emphasis on repair not replacement

    Here at G&S Mechanical we can repair or improve your domestic (household) hot water systems. Whether you system is electric, gas, oil, Heat Pump, geothermal heat-pump, solar or coal.

   While we try to avoid it, there are situations that call for new equipment If you are using propane for your hot water needs we recommend using an instant water heater such as the Aquastar, for larger applications we would recommend either the Hydo-pulse or Glow core. These systems have large capacities and are over 90% efficient and can greatly reduce your standby losses.

    We can also interface into your hot water (hydronic) or steam boiler to produce unlimited amounts of hot water using heat exchanging coils. and your existing or additional storage tanks.

    If your electric water heater fails to work the problem is usually a burned out element or a bad thermostat sometimes a burned off wire will cause problems too. Heaters that use two elements will give priority to the top element to make hot water quickly then switch to the lower element to fill the tank. If the bottom element fails you will have hot water but limited capacity (like 20%). If the top element fails you will have hot water until the top thermostat calls for the element then nothing will happen. Some heaters do not have a top element. When replacing an element do not exceed 4500 watts on a 20 Amp 240 volt circuit. Using a smaller element will NOT save you any money, it just takes longer to heat water.

    If you need to replace a 120 volt element you can use one designed for 240 volts just use a 4500 watt element (the most "common wattage" which works out to 1125 watts) it will last forever. Example replace a 1500 watt 120 volt element with a 5500 watt 240 volt one (works out to 1375 Watts). The tank will start leaking before the element goes bad. The difference between 1125 and 1375 will hardly be noticed, both draw under 15 amps.

    If your heater "pops" the high limit you have a bad thermostat, but you must figure out which one. In rare cases the element can be grounded mid piont and cause the over heating.

    Unless your tank is leaking it is more economical to repair it. If you need to replace you heater we probably can't compete with Lowes or The Home Depot as far as labor is concerned. But they have a tendency to tack on a bunch of extras that can run the price up and not give you a "good job". Like replacing the valve for a humidifier that is leaking.

    If your gas water heater fails due to a bad thermocouple it is definitely more economical to repair it than replace it. If the gas valve fails we may still be able to repair it cheaper than replacing it. If the tank starts leaking replace the heater. Keep in mind that the thermocouples that are used on furnaces are the same ones used on water heaters.

     All water heaters have a temperature/ pressure relief valve on them (usually made by Watts Regulator). Every three months you should open the valve to flush the crud out of it. If it starts leaking replace it. Most valves are rated at 125 PSIG. If you water pressure exceeds 120 PSIG. you should replace the valve with one rated at 150 PSIG. or you will get a relief every time the water pressure changes when you close a valve.
