Hot Water Help

Our client in Sorrento whistled because they were unable to re-light their hot water system, which just means no hot water in their house! Top dog Richard is to the rescue but thoroughly investigates the situation first at the property before simply quoting to replace.

Two hot water systems are enough – Three is too much!

He arrived at the house and tried to re-light the pilot.  They have a Rheem Stellar 330 which has a 5-star energy efficient rating, but it is considerably old, 16 years to be exact.  The flames on this one is yellow and that after some time droplets of water formed around the pilot.  As the area gets hotter the tank expands and causes the water to drip faster which will then take out the pilot light again. Before he proposes to just replace the tank, Richard probes a little further, asking questions from the client and a thorough run through the property. He found out that this home had three hot water system (two Rinnai Infinity 26) which is more than what a regular 4 bath house has. Now talk about a little too much.

Finding The Best Solutions

To fix the situation that the client has and what most plumbers would recommend is to better replace the tank.  Easily quote a new Rheem Stellar 330 and install to solve the problem.  But of course, here at Plumbdog, we not only think of resolving the concern, but we want to provide the BEST resolution that is cost-effective and efficient.  Richard advises a temporary set-up where he connected the tank to one of the Rinnai Infinity 26 and see if it will be enough to supply all four wet rooms. If in the next few days, the family is good with this set up then the best option would be is to have one of the Rinnai’s upgraded to a size 32 instead of replacing the tank. Quality over cost!

• Watch Richard explain as gas fitters in Perth why and some of the rules around the location of where gas hot water systems need to be placed.
• See where the new hot water system has been installed and how it’s reconnected up. You will get a good understanding of what is involved and why sometimes plumbers need to quote for extra works and parts needed even if you’re replacing your hot water system with the exact same model. 

Hot Water System – Straight Swap?

Todays job was originally to replace the a hot water system as a straight swap over.  Top dog Richard arrived at the property and noticed right away that the current system was in an illegal position. As gas fitters, there are specific requirements to adhere to when installing new hot water systems, even if one already exists, and the works of gas fitters are also checked which is a good thing to keep consistency and safety for the industry and our customers.

At this property, there’s only one openable side for the system as opposed to the normal requirement which is two.  It looks like that the system was installed years ago and later on when the owner added an outdoor area it blocked the other openable side.  It is very important that hot water systems are placed in well-ventilated areas. This will ensure that the combustible gases escape safely into the open air and into the atmosphere.  The gases that the system releases have carbon monoxide which is harmful to our bodies.  This gas is colourless, odourless and tasteless so a person would not even know that they are already breathing it until they either pass out or be the cause of death.

Relocating the New Hot Water System

Richard identifies an ideal location for the new hot water system and finds an external wall not too far from the original site which means he will not have a hard time in terms of re-piping.  The new location has two openable sides and he also made sure that the measurements are followed according to the legal standards. This is following 500mm on all sides from corners, wall edges, windows, eaves and the floor.

All The Gear & Every Idea

One visit is all it takes to complete the hot water installation. No need for multiple trips because we made sure that our vans are equipped with high-quality materials, such as pipes, fittings and valves and advanced equipment to make sure that as much as possible our work is “done in one”.  The new system is installed in a new location compliant to the legal standards and safe for the client to use. All in a hot summer’s day work!

Why not replace Gas Continuous with another Gas Continuous System?

In this scenario, the existing Continuous Gas Hot Water System installed in the property was undersized. Unfortunately it’s not as simple as replacing with a newer larger system. For this particular job, replacing with a larger continuous gas hot water system means increasing the gas pipe all the way back to the meter. For this property it was quite a distance between the hot water system and the gas meter which would make replacing the whole pipe quite a costly exercise.

The Solution, a Gas Storage Hot Water System

Our skilled Plumbdogs have the skills and ability to think on their paws to find the best solutions for our customers. Rather than replacing the whole pipe which would be costly, we altered the pipes and made changes to install a Gas Storage Hot Water System.

The Video

Our skilled and experienced Plumbdog takes us through the job and does a great job explaining the whys and hows. If you have an existing hot water system that needs to be replaced, this might give you some insights so that you understand what might be required when a plumber starts to talk about why they can or can’t do something with the hot water system.

More importantly, if a plumber simply quotes and tells you that they have to replace the whole pipe for the unit that you have selected, they aren’t necessarily doing the wrong thing. They are only quoting as requested but they might not have shared insights that you may have other options available which could save a lot of time and money.

• A straight swap is as it sounds where you literally replace a like for like hot water unit.
• It isn’t always as straight forward as pulling out the old and connecting the new hot water system. We explain why.
• Compliance and safety are of utmost importance for the household.
• Testing the hot water system properly after installation is equally as important.

Different Types of Hot Water System Installations

There are different types of hot water systems including electric, gas and solar hot water with different options like storage or continuous flow and with a range of brands available and even housing designs, no two jobs are the same.

Because of the different number of scenarios, most plumbing websites advertise prices with installation for what we call ‘straight swaps’ or ‘like for like’ which is the base minimum to get an existing unit replaced without having to install new pipes or any major modifications in order to get the new hot water system installed.

Usually what will happen is:

• Unit is purchased with installation
• Plumber will arrive and check a few things to make sure the new unit can go in.
• If changes are required, then an estimate is provided and payment taken on site for the changes required to get the hot water system installed.

[Note: There may be some scenarios where a straight swap is not permitted. For some properties the location of the hot water system is not compliant with current regulations. You may have seen in our recent blog where a hot water unit was too small for the property. We changed from a gas continuous flow to a gas hot water storage unit to help reduce costs of installing completely new pipes]

Today’s Video: A Straight Swap of a Gas Continuous Flow Rinnai Infinity B20

For the job today, we have a straight swap of an old and new system of the same make and model which makes it relatively straight forward. Important to note however that just because it’s a straight swap, there is still the possibility that the new unit may not be installed.

To start off with before installing, our obedient and compliant Plumbdog makes some checks.

Initial Checks:

• The supply pipe is ok. Check.
• The pipe on this property is close to the gas meter. Check.
• The Hot Water System is not close to windows and doors. Check.
• The System is not too close to the flue and at least 300mm from the eaves. Check.

Everything stacks up and a straight swap is ok which means no extras to our customer and the price is as advertised on the website.

Testing After Installing the Hot Water System

Even though we’ve literally replaced everything as it was and connected the pipes to the same places on the new unit, our job doesn’t stop there. We need to test to make sure everything is functioning properly.

Test Gas Pressure

We test using a gas gauge to make sure the right gas pressure is flowing and performing properly. Too much or too little gas has an effect on performance which leads to unnecessary costs to you when running the hot water system.

[Plumbdog Tip: Check for the red tape under your system to see if it’s still there. If it is, then most likely the plumber hasn’t checked the gas pressure]

Test Temperature Inside the House

The fact that manufacturers are putting signs to check temperatures after installation means that there are plenty of installers out there who are not adequately testing. This is part of our standard procedure. Even though the hot water unit is supplying water at 50 degrees Celsius, there are numerous reasons why 50 degrees isn’t achieved inside the house and we need to adjust accordingly.

At Plumbdog, we hold our plumbers to high standards and have procedures for safety and compliance for the safety of our customers and our team. Following these procedures means that our customers enjoy a hot water system that works efficiently providing hot water while operating efficiently burning the gas and not your hard earned money.
