Modern Gas and Electric Hot Water Systems
Hot Water Systems
Modern hot water systems have advanced significantly compared to their old-school counterparts. We often get requests for mains pressure cylinders to remedy low water pressure problems. Smart options, such as continuous flow hot water systems, are becoming increasingly popular for new homes due to their efficiency and compact nature. Moreover, modern electric units are highly reliable and powerful, provided they're correctly installed by a licensed professional like the experts at L B White.

Modern Hot Water Systems: Modern hot water systems have advanced significantly compared to their old-school counterparts. Smart options, such as continuous flow hot water systems, are becoming increasingly popular for new homes due to their efficiency and compact nature. Moreover, modern electric units are highly reliable and powerful, provided they're correctly installed by a licensed professional like the experts at L B White.
Hot Water Cylinder Failures: Hot water cylinders are designed to last for several decades. However, signs of wear and tear, such as low water pressure or a complete lack of hot water, can indicate potential issues. These problems could arise from a cylinder leak, rust, or an electrical fault. Our experienced team can quickly identify the issue and advise you on the best course of action, be it an immediate fix or a complete unit replacement.
Hot Water Cylinder Maintenance: Regular maintenance is key to ensuring the longevity of your hot water cylinder. At L B White, our comprehensive cylinder service ensures your equipment operates efficiently. Regular maintenance checks are significantly more cost-effective than emergency call-outs, protecting your investment in the long run.
Heat Pumps - A great alternative to traditional systems of heating. You can expect substantially less power than your conventional hot water unit. The Eco Plus and the Ambi Heat products are great examples of electric heating to save you money on the power bill in the long run.
DLM Wallace Lead Sheet / Acrylead
DLM Wallace Lead Sheet & Acrylead consist of virgin lead of at least 99.8% purity, machine cast in to sheet form of various dimension and thickness. Acrylead has a factory baked acrylic primer coating which inhibits the contact of water with the lead and its oxides, greatly reducing lead run-off which can cause staining on surrounding roof materials such as tiles. Lead Sheet & Acrylead are soft and malleable, making them a versatile flashing material. They offer strong resistance to corrosion and UV degradation, offering unparalleled longevity of service.
Scope of use:
Lead Sheet & Acrylead are used as a flexible weatherproof flashing to drain or deflect water back outside roof
and wall cladding systems. They are commonly used for flashing concrete, clay and slate tile roofs, for buildings described in Table 1 of NZS 3604:2011, and NASH Standard Part 2: May 2019- 1.3.1.

· Parallel flashings must be dressed down in to the tile pan, and have a minimum cover of 150mm, with a minimum upstand of 100mm (75mm minimum upstand behind cladding). Refer NZBC E2/AS1- Figure 26.
· Transverse flashings must have a minimum cover of 150mm over the tile, and have a minimum upstand of 100mm (75mm minimum upstand behind cladding). Refer NZBC E2/AS1- Figure 26.
· Flashings should be designed so that while the lead is in position, free thermal movement is not restricted.
· Nails, screws and fixings should have a similar life expectancy, and thus should be copper, or stainless steel.
· When forming and shaping lead, caution must be taken to not over-stretch the lead, which can create thin areas with reduced integrity.
To reduce the risk of run-off staining surrounding materials, a patination oil should be applied to un-painted lead sheet as soon as possible after fixing. Acrylead should be over painted with a quality acrylic external house paint and this coating should be maintained.

Types of Products
There are three distinct types of hot water cylinders, each offering different benefits. Understanding these systems will help you make an informed decision about the best option for your home or business.
Gas Hot Water Cylinders: These are typically smaller than their electric counterparts as they can heat water at a much faster rate. If you're looking for a compact yet highly efficient solution, gas hot water cylinders might be the perfect choice.
Electric Hot Water Cylinders: Electric systems heat the water inside a storage tank, operating much like a kettle. Available in various sizes, these are the most affordable options on the market. However, it's worth noting that they are generally less energy-efficient than other systems.
Gas Continuous Hot Water Systems: These systems heat water only when you turn the tap on, providing a continuous stream of hot water. This setup can offer a range of benefits, such as significant savings on your energy bill and reduced climate footprint. If you have a large household or are tight on space, a tankless system could be an ideal solution.
