5 Central Heating

Podcast cover
Read more

In today's cast, I complete our introduction to heating systems with a look at central heating. 

Common to all central heating systems are three main components:

1. The fuel

2. The engine or heater

3. The distribution system - pipes, ducts and outlets

There are two main mediums for transfering heat. Air is common with gas-fired heaters and large ducts but is not as effective as water based systems.

Air ducts can lose up to 1 degree per m of duct. 

Heating that is not true central heating includes inslab or undertile electric element heating, heat transfer and ventilation system.

13 Do you need a ventilation system?

Podcast cover
Read more

About 10% of New Zealand homes invest in some form of retrofitted ventilation system. But do you really need one, and if so, what for?

In this cast I talk about how to tell if your house is leaky or air-tight depending on it's age, two basic types of ventilation systems and the common symptoms that cause people to want to install a ventilation system. 

Steps to take when considering ventilation are:

  1. What's your problem?
  2. What's your house type?
  3. Insulation
  4. Draughts 
  5. Adequate heating
  6. Extraction of moisture at the source
  7. Whole-house ventilation

20: How to Insulate a Concrete Floor Slab

Podcast cover
Read more

Why should you insulate the edges of your concrete slab? 

I was amazed when I discovered how much of the heat loss from a concrete floor can occur out the side of the slab, as opposed to down into the ground under the slab. 

It's as much as 80%. 

That means that most of the heat loss (the energy that you're paying for) goes straight out through the narrow bit of exposed concrete around the edge at the base of the house.

Why is this so? Well there are two main reasons and I go into a bit of detail on the blog. Check out http://homestylegreen.com/insulated-concrete-floor

In this podcast we talk solutions. I interview Craig Lonsdale, a Quantity Surveyor with Maxraft. 

Maxraft is a great solution for insulating the whole of a concrete floor, not just underneath.

17 What you need to know about heating

Podcast cover
Read more
One of the most common questions I get asked is "what's the best form of heating?"

Much to the frustration of most people, I usually answer "it depends…" The best type of heater for you and your home does depend on many factors, however there are some guiding principles that apply to all cases.

  1. The most sustainable form of heating is passive
  2. The second most sustainable form of heating is wood
  3. Heat pumps (split-system, reverse-cycle air conditioners) are single room heaters
  4. Homes with solid fuel burners are generally warmer than those with electric heating
  5. Your roof won't heat your home
  6. Water is much better at moving heat around then air it
  7. Insulation is always the first step
  8. Insulation is not heating

In 2003, thermal performance requirements for residential buildings were added to the Building Code of Australia for the first time.

In 2006, the requirement rose to 5 Stars, then to 10 Stars in 2010. This all sounds great. The increasing rating requirements of NatHERS provides a measurable and predictable target for improving the energy efficiency of Australian homes.
