Continuous Flow Hot Water System

We have seen a rapid increase in the use of Continuous Flow Hot Water Systems in the last 20 years. This is largely due to the face that “continuous flow” systems heat the water as you need it so you never “run out” of hot water. They are compact in size and can be mounted internally or externally depending on your needs. Most have a 5 star efficiency rating as they heat the water as you use it reducing your carbon footprint.

Mains Pressure Hot Water System

Hot water from these units use mains pressure to hot water at a similar flow to cold water. The water is heated and stored in a tank which as most commonly placed outside. Once the tank is empty you run out of hot water and need to wait tor the tank to refill with cold water which then has to be heated. The tanks are larger in size and you can still manage a 5 star efficiency rating despite having to heat larger volumes of water. Mains Pressure Hot Water Systems are cheaper to install.

Gravity Fed Hot Water Systems

Despite being one of the most reliable hot water systems they are FAST becoming obselete. Gravity Fed Hot Water Systems are most commonly found in the ceiling of older homes or businesses and the water is heated by electricity. They rely on gravity to deliver the hot water which is usually at a much lower pressure and flow rate to the cold water. They are mostly replaced when they start to fail or as people renovate as modern tapware and water saving devices are largely incompatible with gravity fed units. 

Frequently Asked Questions:

1. Why should I hire a professional plumber for my hot water repairs?

Hot water systems are intricate and require expertise; entrusting them to an amateur or unlicensed contractor could lead to voided warranties and jeopardise future insurance claims. There’s a risk of them solving one issue while inadvertently creating a more dangerous one. Above all, this places your home, family, and staff at risk.

By choosing a licensed plumbing company like Doherty Plumbing Solutions, you ensure that the assigned plumber possesses expert knowledge of the equipment and can repair or replace your hot water system without causing further damage. Our team is well-versed in all the models from the leading brands, ensuring your system operates flawlessly once again.

4. Do hot water systems affect gas and electricity bills?

As your hot water system ages, its efficiency decreases, leading to energy wastage during water heating. Consequently, the system will run for longer periods to reach the desired temperature, resulting in higher energy bills. If you notice a sudden increase in your bill, don’t hesitate to reach out to Doherty Plumbing Solutions for a prompt system check.

    Expected attendance time was managed well with calls and alerts prior to. People were respectful, friendly and professional. Problem was quickly diagnosed, fixed and tested through appliances. Clean-up afterwards was greatly appreciated and a step above other service providers. Used Doherty a number of times, very happy to recommend them.
