Karl and his team were great. Karl provided us with an in depth summary of the range of work required up front. He took time to explain what was required and highlighted the potential issues with an install. This proved to be really helpful in understanding how much work, time and cost was required. His estimate was fair and realistic. While the install took an extra day and a half which was longer than expected, he kept us informed along the way and took the time to ask and seek direction if issues arose with the install (e.g. placement of vents that couldn’t go where we originally wanted them to, location of fresh air intake vents and gas flues). While Warmzone’s quote was more than the competition it was far more realistic and detailed. We would rather the job is done well and done once and Karl and his team provided us with the confidence that they would deliver. In retrospect we doubt the competition could have delivered for their quoted figure and certainly without cutting corners. The Warmzone staff kept our home clean and tidy during the install which is important to homeowners who still have to keep a busy home operational. We are thrilled with our new central heating and infinity water and wouldn’t hesitate recommending Karl and his team. We have yet to experience Warmzones after-sales and servicing but based on our experience so far we expect it to be top-notch.

I have kept a record of our monthly energy costs since we moved here (almost 9 years ago) and I can tell you that our monthly average energy bill decreased from $158 per month in 2009 to $144 per month (a drop of 8.4%) in 2010. (We installed the gas central heating at the beginning of July 2010.) Our biggest monthly bill last year was $252 in September. This is in a house of 150 sq metres and two adults, where there was someone home all through the winter.

We are extremely pleased with the heating system and the outstanding after sales service that your company has given us. This even included on site visits to assist us with the setting of all ‘extras’ this system has to offer.

I have found the Brivis central heating system absolutely fabulous! It has to be the best investment I have ever made in my home and I would recommend it to anyone wanting a heating system. The service I received from Karl was great. He was friendly, reliable, efficient and his workmanship was 1st class. Thank you once again.

We would recommend Warm Zone to anyone considering introducing the Brivis gas central heating system to their home. Karl is awesome to work with and guided us every step of the way with his expert knowledge. Our large family home is heated within 10 minutes at the push of a button. We are extremely pleased with the end result and would gladly recommend you to others.

I have been very happy with the Brivis heating system, I will tell people I know about Warm Zone. Karl and team were great, putting system in and cleaning up after them, which means a lot, thank you.

Thanks again for the perfect installation on our central heating system. The house heats in 10 minutes and is easy to operate. It has run faultlessly for three years. We recently had the three year service done and a local service agent remarked on the quality of the installation – which is why I am writing to say thanks. Interestingly – it is costing little (if any) more to operate than our free standing electric heaters did – we had three and had to choose which rooms to heat.

Now we have the whole house warm, the ambient temperature of the house is higher and we have warmer and happier kids at night. We couldn’t be more satisfied with the system and installation. I recommend WarmZone to anyone currently wondering what heating option to choose. Many thanks for the advice, the system and our warm home. I wish you well for the future.

Mike and I would like to express our gratitude to you for the amazing improvements you have made by increasing the performance and output to our existing central heating system. Not only were you extremely diligent throughout the time your company was here but also the work was carried out to a very high standard. We would therefore have no hesitation in highly recommending “Warm Zone Ltd’ as a preferred company to deal with.
