How To Choose The Best Tankless Water Heater
First of all, let me clear a few terms for you. If you hear tankless water heater, on-demand water heater or instant water heater, they all point towards the same product, i.e., a water heater that doesn’t take time to heat water. Hot water is readily available in such water heaters. Now, coming to the main discussion, i.e., how to find the best water heater, so there are a few factors that you need to consider before finalizing a water heater, which we will discuss now.
Gas Vs. Electric: As you must have seen in the aforementioned reviews, two types of tankless water heater exists in the market, one that operates on gas and another, which runs on electric power. Each version has its own pros and cons. Where gas-operated water heater runs on either natural gas or propane, it is going to be cost and energy-efficient. Gas water heaters are also more powerful than electric water heaters.
Despite having an upper hand over electric water heaters, gas-operated units are not the first choice for many people due to their high upfront cost. The cost of the unit is high and then, you will have to shell out money at the time of installation as well, so the overall cost becomes very high. If you are more inclined towards having an environmentally friendly model, then you can buy an electric version, which even runs on solar power. You can buy a solar panel and connect the majority of your household’s electrical appliances with it including an electric tankless water heater.
Hot Water Demand: When buying a product like a water heater, you should pay attention to the maximum flow rate of the unit, which is calculated in GPM or Gallons per Minute. The higher the value of GPM, the more efficient the water heater is. Bathroom showerheads have the highest flow rates, which is between 2.5 to 3 GPM for high-flow showers and 1.5 GPM for low-flow showerheads. If you are unable to fathom this calculation, then just keep in mind to buy a powerful tankless water heater with higher output capacity.
Climate: If you live in an area where everything freezes during winters, then you need a water heater with higher flow rates. The requirements can be reduced when you are living in an area where it doesn’t get too cold in winters. It is better to pay extra and get a powerful unit if you are living in a region where weather gets extreme because you will be able to save energy as well money, as it is not that easy to heat water in winters.
Installation Costs: As I have mentioned above, gas water heaters are more expensive to install. You will be charged around $300 or more for installing a gas tankless water heater. If you believe in DIY and have some knowledge about installing water heaters, then I will encourage you to install the unit on your own and save those installation charges.
Warranty: Like all other products, you should pay attention to the warranty part of a tankless water heater because there are many parts in a water heater, which are prone to damages or malfunctioning, so a longer warranty will help you repair or replace those parts easily.
The whole discussion boils down to the selection between electric and gas-powered tankless water heaters. Both have certain advantages and disadvantages, so it is up to you to decide as to which type suits you the best. If you need a more powerful water heater, then go for a gas water heater, and if you want an eco-friendly unit, then an electric water heater will suit you more. Choose one product from the six best tankless water heater consumer reports after going through reviews and I’m sure you will be able to buy the right product.
