What to consider before you buy a water heater

 

Purpose

Domestic water heaters are mainly of three types: the central heating system, the standalone units for bathrooms and kitchens, and the immersion heaters. In tropical countries, you rarely find the standalone units in kitchens. People also use immersion heaters to achieve water heating. Depending on the design, the central heating system could hold up to 170 liters of water. The standalone units on the other hand could hold up to 50 liters of hot water.

The number of people using a single unit will inform the capacity to purchase. It should be noted that larger capacity heaters will require more energy to heat up the larger volumes of water they hold. Also the frequency of use will mean continuous operation of the heating element. Factors to consider are the capacity, the frequency of use and the product brand performance.

Power Consumption

Typically the central water heating systems require about 4,000 watts of energy, while the individual ones consume around 1,500 watts. The immersion heaters (boiling ring) range from 600 to 1500 watts of energy.

Warranty

Always remember to check for warranty. The duration of the warranty determines the confidence the manufacturer has in the product. Therefore the longer the warranty, the more confident the manufacturer is that the product is durable. Never buy an appliance with no warranty! Finally, you should buy from an authorized dealer to ensure that the warranty is valid.

Brands

There are many dehumidifier brands in the market. Always check for the SONCAP certificate, as well as the warranty (as said above). Additionally you can check our blog for reviews and ratings of dehumidifiers.
