What to consider when purchasing a mini tank water heater?
It is important to pick a durable and efficient heater for your home but before doing so you have to take into account the size of your household. There are tanks as small as 30-40 gallons, medium sized of around 50 gallons and of course larger capacity ones over 100 gallons. These heaters are able to be used with the smaller tanks that you can find in the market. Depending on the model, each heater runs on different fuel so ideal you should pick a heater that runs on fuel that is affordable but also readily available to your location.
The most common ones are electric heaters due to their lower cost but on the other hand, you can also shop for natural gas or propane heaters if you are more convenient with them. There are also solar power heaters in the market but they are not a budget-friendly option at the moment. If you can’t decide we would advise you to go for an electric heater but just have a look at their energy efficiency before purchasing.
Pick a water heater from a reputable brand so that it will be backup up by a long warranty and would be more likely to get replacement parts if needed in the future. If you are going to use the water heater for long periods of time you may need to invest a little more and get a model with the highest energy efficiency. Such mini-tank water heaters can also be placed under the sink providing an adequate amount of warm water for your bathroom and kitchen, but also a great option for cottages and camps.
They are normally easy to install and they are ideal solutions for instant hot water delivery with minimum waste of water heated. You can also install them in a remote location like your garage if that’s what you prefer but you have to keep in mind you need to winterize it if you live in a cold climate according to manufacturer’s recommendation.
Mini tank heaters are limited to the amount of water they can heat in an hour to take the time to measure the amount o points you want hot water to like a dishwasher, a washing machine, a shower, so as to have a better estimate of the size of the tank size you may need to pick. Moreover, if you live in a big house, it may be wise to have water heaters in any remote locations where the hot water form your central heating might take too long to reach as a cost-effective solution.
