Types of Hot Water Systems

There are several hot water systems to choose from when replacing an old system or building a new house. Knowing the differences is important to picking the right option for your home. Here at Murphy Plumbing, we are the experts in all kinds of hot water systems in Newcastle and can help you choose which one works best for your needs. We can then install it and maintain it for you. Here are the most common types of systems.


Heat Pump Hot Water System

Instead of using coils or natural gas to heat your water, this kind of system pulls heat from the ground or the air. It’s an electric system that works well in warm climates, but not as well in cooler locations. This model is much more energy efficient than many other options, but sometimes requires more space than other kinds of hot water systems.


Solar Hot Water System

By using the energy from the sun, this kind of hot water system absorbs the heat and transfers it to the coils inside the system so it can heat your water. It’s ideal in sunny places and can save you a lot of money on your energy bills, especially in the summertime. This system is more expensive than others and may not work well if it’s not sunny outside.


Gas Hot Water System

A gas water heater is a water heating system where the main fuel used is gas. There are two main types of gas water heaters: gas continuous flow and gas hot water storage tanks.


Electric Hot Water Systems

This is the most common kind of hot water system and consists of a tank that is insulated and that stores your hot water. You can then use it from the faucets in your house when you need it. This kind of hot water system requires regular maintenance and is one of the lowest cost options out there. A tankless hot water system is great because it heats water on demand, using water filled coils. This system usually costs more up front but is more energy efficient and can save you money in the long run. This system is ideal for large families but should be serviced once a year for optimal performance.

Frequently Asked Questions

How do I decide which hot water system is right for me and my property?

It’s important to choose a hot water system that is within your budget and you can do this by comparing the costs of reputable systems online or in-store.


You should also consider what you need from your hot water system (e.g. the size of your household or property and the frequency of use) as well as what your property can support.

What size hot water system do I need for my property?

For large family households (upwards of four people), you will want a hot water system with a tank that can hold 50-80 gallons of water at any time. However, smaller homes will only require between 23 and 36 gallons in their tank.

When do I need to replace my hot water system?

Typically, we recommend that you upgrade your hot water system and tank every 10-15 years or tankless system once every 20.


Although, if you notice any faults, damage, or wear with your current hot water system, you should get in touch with your original supplier and consider upgrading sooner.
