Case Study

Company: Pipeline Central Heating
Location: Newtown, Wellington.
Age of home: 1920’s
Area: 120m²
System description: Gas boiler radiator heating with DHW production.
Main components: Delonghi PHD radiators,  Baxi Duotec 40GA combi boiler, Heatmiser NEO controller.
Design criteria: Bedrooms to 18 degrees and living areas to 21 with an outdoor temperature of 3.

Homeowner discussion: The existing homes heating consisted of an old gas fire in the lounge and electric oil panel heater in other key areas.  We were asked by the homeowner to provide a thorough heating system that heated the whole home if required but had the ability to isolate certain rooms if they weren’t being used.  She also wanted the convenience of fully programmable controls as her work schedule changed daily.  The obvious choice in this case was radiator central heating with a Heatmiser programmable timer and thermostat.

During the consultation we noticed that the existing hot water system, an old gas hot water cylinder, was looking very worn and near the end of its life.  The suggestion was put to the client that a ‘combi’ boiler would be a great addition to the home.  This would involve the removal of the existing hot water cylinder and connecting it to the brand new boiler that provides both instantaneous hot water and central heating in one.

Installation summary: A smooth installation. Full access to the plumbing underneath the home was definitely a bonus, and not typical for homes in this area.

There was a concern about the look of a white radiator in her entry/hall way, which is lined with timber paneling and stained glass windows.  The suggestion was made to colour the radiator to blend in with its surroundings.  The valves and thermostatic head were upgraded to chrome which created a fantastic looking addition to the entry area.

Customer verdict: A warm healthy home with an amazing high pressure hot water system.  We have since returned for the annual service and the homeowner said it was the best choice she ever made for her comfort.  A great result!

Member Profile

Name: Phil Reed

Company: Gas Serve Ltd

Trade history: I started my apprenticeship in plumbing and gas back in 1995 working on old villas in Devonport. I finished my apprenticeship in 1999 and swore I'd never work on another villa again in my life. Fast forward 20 years, 80% of our heating work is retrofit to villas and I live in one.

How you found the heating industry/ how it found you: I came back from an OE in 2007 having worked on a few radiator systems over there. A customer here asked If I knew anything about them or could source them here in Auckland and the rest is history.

Length of time in the heating industry: 12 years in hydronic.

Favourite heating product and why: Simple things. Pre-insulated pipe systems. So quick, tidy and effective. especially in a 300mm crawl space under villas!

Describe yourself in three words: In the office I'm called "Central Heating Guy". We are a creative bunch.

Ford or Holden: Yamaha

Favourite Sport: Anything my kids are playing or anything on 2 wheels

Best piece of advice you've ever been given and by whom: Keep the main thing the main thing. Can't remember who told me that but I'll bet they were wise.

Do you have any pets: Well, I've got a dog, we had 3 rabbits but now there are 27. I've currently got a nice .22 cal on my TM watchlist.

Last word (anything you desperately want the world to know): The hydronic industry has huge potential here in NZ and its very rewarding selling something you are truly passionate about.

Technical Tip

A hot water heating system is in general designed for a maximum heat load at minimum design outdoor temperature, this means for 95% of the time the system is oversized and the control system has to start and stop the system to prevent it from overheating the space.

A lot of the modern heat sources now feature temperature compensation which varies the water temperature pre-emptively using the outside and inside air temperatures as a reference.

This allows the heating system to modulate rather than just switch on and off.  This increases the overall efficiency and comfort of the heating system providing both low running costs and more comfort.  Ask your heat source supplier what options they have.
