  • What do I need to know in order to purchase a water heater over the phone?

    The information that our representatives will be asking for includes: the model and/or size of the water heater you currently have. This tells them what fixtures and materials you will need.

    The best way to prepare for that is to photograph your tank or write down the brand name and model information and have that available when you call us. We can quickly get your quote and you’ll be ready to schedule an installation.

  • Is it really a limited lifetime warranty?

    Yes. There is a limited lifetime warranty covering the tank itself, however to get it, you must register the product on the HTP website: within 90 days of installation or it defaults to a 10 year tank warranty.

    Labor is not covered but we charge a flat rate $350 for warranty labor in replacing your tank.

    The warranty requires that you maintain the tank by occasional flushing to remove build up of minerals. If you are uncomfortable doing your own tank flush, our plumbers do provide that service. See full warranty details on the Everlast warranty PDF.

  • Why is this Seattle’s best electric water heater?

    Most electric hot water heaters last eight to ten years. The Everlast water heater costs more than a standard tank but will last longer. There is a heating element that will need replacing about once every decade (10 yrs.). That costs about $300, a lot less than replacement cost for a standard tank. If you are 30 years old and a homeowner, you might buy 5-6 tanks before you are 80. That could cost $8000 or more. With this HTP Everlast tank and with good maintenance, you will keep your tank healthy and have the added benefit of not worrying about a failed tank leaking in your home, for life.
