  • CAUTION: It is highly recommended that you only use a ground fault circuit interrupter (GFCI) outlet. The said outlet should be in a weatherproofed location adjacent to the tank where you intend to de-ice. Avoid using extension cords as it is can cause power drops that in turn cause the de-icer's poor performance. Always consult the included user manual for safety and maintenance guidelines.

Regarding the 300 btu pool heater I have a preference for the products of the brands listed below.

  • 5 Things You need to consider when choosing the 300 btu pool heater

    There are some things you should consider when buying a 300 btu pool heater. We spent 22 hours researching the most important things you should consider when buying a 300 btu pool heater. So should we start with the list of things you should consider?

    1. Budget and price matching

    Make a list of the things you want in your 300 btu pool heater and the price you are willing to pay for it. So try to look for a product in that price range and choose the one that appeals to you the most. One tip we would like to give you is: don’t settle for a cheaper product if it doesn’t even have a function you need.

    Most 300 btu pool heaters fall within the price range of $ 349.95 to $ 396.36. Therefore, if budget is not a problem and you want the best product for your needs, we advise you to choose the Hydro Quip Hotspring Replacement Heater Assembly 1.0/4.OKW 120/240 Volt.

    If you want something medium range, choose Hayward W3H400FDN Universal H-Series 400,000 BTU Natural Gas Pool and Spa Heater for In-Ground Pools and Spas. If you have a very low budget, you can choose the one that is the SunHeater Pool Heating System Two 2’ x 20’ Panels – Solar Heater for Inground and Aboveground Made of Durable Polypropylene, Raises Temperature, 6-10°F, S240U

    2. Does it have all the features you need?

    Most importantly, the 300 btu pool heater you are purchasing should have all the features you are looking for. In case you don’t even have one, don’t buy! We are saying this because you will not be able to use it for that purpose. If you are a person without budget problems, I would suggest you to choose the best model which is SunHeater Pool Heating System Two 2’ x 20’ Panels – Solar Heater for Inground and Aboveground Made of Durable Polypropylene, Raises Temperature, 6-10°F, S240U

    3. The brand

    Buying the 300 btu pool heater from a reputable brand can actually make sense. Not only will it be better than others in terms of “build quality”, but it will also have some extra features, better customer support. Famous brands have multiple service centers across the country, so if you have any problems you can simply take your 300 btu pool heater to one of their service centers.

    4. Warranty Matters!

    When you buy a 300 btu pool heater from a well-known brand, you will get a guarantee. Low-cost products also come with warranties, but the claim process could be tougher. That’s why I always suggest you buy the product from a reputed brand and the one that comes under warranty. It will save you from repair costs in the future. On average, around 21% of people end up paying 40% of the product price for the service! You can save on service costs if the product is under warranty!
