On buying a new home, or renovating your house, there are multiple decisions to make and endless things to purchase. From flooring to room dcor, everything remains on our to-do list. But what we often do not give much importance to, is the water heater, which is, actually one of the most important home appliances. Picking a good water heater is not an easy task and requires a lot of research work. In this article, we will look at an often asked question, “Which water heater is the best for your home: Tank or Tankless”. Read on to know!
Storage tank water heater
Tank water heaters are available in two variants- gas and electric. They are insulated and keep the inner water warm, and have a thermostat to control temperature. Given below are some of their pros and cons.
• It has lower maintenance and repair cost than a tankless water heater. It only requires draining and flushing twice a year, and testing the pressure relief valve regularly
• Fewer installation complications
• Easily adapted to re-circulation and solar pre-heat applications – this is particularly ideal for desert areas
• Lower replacement costs
• Storage water tanks take up a lot of space. If you have limited floor or even wall space, this may not be suited for you
• These water heaters have a shorter lifespan which is about 10-15 years
• More energy is used to help maintain the temperature of stored water due to reheating water to ensure it is a pre-set temperature. This leads to higher utility bills
• The water in the tank gets heated to the limit of the size of the tank. This would be a limited hot water supply
Tankless water heaters
Tankless water heaters are convenient and energy-efficient and provide endless hot water supply. Instead of storing heated water in tank, it supplies water only when needed. We have listed below, a tankless water heater’s pros and cons.
• A tankless water heater usually lasts between 20-30 years, which is almost double the life of a storage tank water heater
• Tankless water heaters are small and can be installed in tight spaces
• You will never have to wait to get hot water. Tankless water heaters can deliver 2-3 gallons of hot water per minute
• Tankless water heaters can reduce energy cost by 25% as the energy is not used until hot water is needed
• Tankless water heaters have a higher purchase cost than a traditional storage tank
• Limited output: You cannot do multitasking because it does not store a huge amount of water and can serve only one shower/purpose at a time
• If you are replacing a storage tank water heater with a tankless water heater, the replacement can be pricey
• Requires regular professional maintenance
• Because there is no water storage, you don’t get hot water supply in case of a power cut
• Low flow rate: If the flow rate for hot water falls below 0.5 gallon per minute, the unit will not sense a draw and will not continue to heat water
