  • How to choose the best instant hot water heater

    There are some things you should consider when buying a instant hot water heater. We spent 22 hours researching the most important things you should consider when buying a instant hot water 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 instant hot water 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 instant hot water heaters fall within the price range of $ 159.95 to $ 416.86. Therefore, if budget is not a problem and you want the best product for your needs, we advise you to choose the Bosch Electric Mini-Tank Water Heater Tronic 3000 T 2.5-Gallon (ES2.5) – Eliminate Time for Hot Water – Shelf, Wall or Floor Mounted.

    If you want something medium range, choose Bosch Electric Mini-Tank Water Heater Tronic 3000 T 7-Gallon (ES8) – Eliminate Time for Hot Water – Shelf, Wall or Floor Mounted. If you have a very low budget, you can choose the one that is the Rheem RTEX-18 18kW 240V Electric Tankless Water Heater, small, Gray

    2. Does it have all the features you need?

    Most importantly, the instant hot water 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 Rheem RTEX-18 18kW 240V Electric Tankless Water Heater, small, Gray

    3. The brand

    Buying the instant hot water 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 instant hot water heater to one of their service centers.

    4. Warranty Matters!

    When you buy a instant hot water 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!
