Important things to be considered when choosing an under sink water heater
- Size – Size is one of the most important considerations when purchasing an under sink water heater. You should determine first how much space your kitchen or bathroom has. Calculating the space will enable you to determine the size of your under sink water heater. This will prevent you from having problems in trying to fit the device to your kitchen or bathroom.
- Capacity – Capacity is also an important factor that you should keep in mind when choosing an under sink water heater. You should know how much hot water you need on a daily basis before so that you will get the right capacity. Under sink water heaters are available in both tank (2.5 to 7 gallons) or tankless options. If you need more hot water, then you will need a larger tank.
- Energy efficiency – Cost will also be a significant factor when choosing an under sink water heater. You want to save on energy costs while getting all the hot water you need. Fortunately, under sink water heaters are usually more energy-efficient than traditional water heaters. But if you’re really concerned about the cost, then you’ll have to look specifically for the energy-saving units, which will help cut down on your electricity bill.
- Safety features – Choose under sink water heaters that have the proper safety features. Some units feature a thermostat, which makes heating water easier and safer to use. Others come with a temperature control where you can adjust the temperature of the water to your liking. Modulation is another safety feature that lets you change the heat output in response to the flow rate of water running through the device. This safety component helps maintain your water’s temperature no matter what the flow rate is.
- Installation – There are many varieties of under sink water heaters, and each of them has different installation and maintenance requirements. Some units are quite easy to install – all you have to do is to simply plug the unit into an outlet and, voila! It is now ready to use. Others, though, may require more plumbing and electrical work to make it functional. In this case, it’s better to hire a professional plumber or electrician for the installation process. Make sure that you understand the different installation and maintenance requirements before making a purchase.
- Price and warranty – Under sink water heaters are available in different price points. Before purchasing a new unit, first you have to be clear about your needs and, of course, your budget. But if you’re really looking for a longer-lasting unit, always choose the one with a superb quality even if you have to pay a bit more. Another, choose a unit with a warranty. The longer the warranty, the surer you can tell that the product is durable.
Types of under sink water heaters
There are two main types of under sink water heaters. Your choice of an under sink water heater depends on how much power you will allow it to consume and how fast you want the hot water to get to the faucet.
Tank heater – The tank heater consists basically of a heater with a tank or compartment that stores hot water for ready use. The tank water heater normally heats up a small amount of water after it is turned on. Afterwards, it will store the heated water until it is released through the faucet and onto the sink. The average amount of water that the tank under sink water heater stores runs from 2.5 to 7 gallons, which is enough for providing hot water for two to three people in the morning.
Of the two types, the tank type is easier to install because you would only need to connect it to the water supply and to the sink. But there’s one downside, though – it provides only a limited supply of water. It means that after using up all the hot water stored in the tank, you’ll have to heat up another small amount of water again, which takes a bit of work.
Tankless heater – As the name implies, this type doesn’t use a tank to heat and store water. Instead, it automatically heats up the running water on the supply and through the faucet. With a tankless under sink water heater, you will have a continuous supply of hot water without having to reheat it.
If there’s no water running through the pipes, the tankless heater will stay turned off until you turn on the faucet. As it doesn’t use a tank to store hot water, the tankless option is smaller compared to the tank heater.
The number one advantage of using a tankless heater is obvious – you’ll have hot water instantly whenever you need it. Another advantage is that it doesn’t require a lot of space, unlike the tank variety. Plus, you don’t have to wait a few minutes – or even a number of seconds – for your water to become hot.
However, the obvious drawback of a tankless heater is that it can be pretty complicated to install. You would have to properly connect it to your home’s water supply by calibrating the pressure and checking the wirings in order to make it work.
