topway SLM

Type 2 Topway SLM Single Loop Manifold

Based on the tried and tested Emmeti Topway Type 2 manifold, the SLM Single Loop Manifold offers a solution to single zone underfloor heating

Typically, the manifold would be used for adding an underfloor heating circuit to an existing system such as in a conservatory or extension.

Supplied in 1”, complete with automatic air vents, drain and fill valves and end caps. Provided with a single, integral double regulating flow meter. Can be surface mounted, concealed in a cabinet or within a partition wall. Manifold flow and return outlets are offset.

Also available are ball valves, Monoblocco pipe connectors, electrothermic actuators and matching zone controls to meet or exceed Building Regulations Part L requirements.

Technical Data

The SLM manifold is designed to allow the connection of an underfloor heating circuit with individual time and/or temperature control of the circuit. Using an Emmeti T3 Control Set with the SLM Single Loop Manifold will allow the primary flow and return temperature to be controlled to a temperature suitable for underfloor heating if a low temperature heat source is not being used.

The SLM manifold is equipped with an electrothermic valve body for use with Emmeti standard electrothermic heads which allow electrical control of the circuit either by a programmable or standard thermostat. Used with a four-wire electrothermic head which includes an auxiliary switch, this also allows electrical interlock with the boiler and pump as required by the Building Regulations.

FAQS

Why do I get a bubble in the top of the flow meter?
There can be a small residue of air in the top of the flow meter. The higher the filling flow rate, the less air there generally is. As long as it is above the reading scale, it does not affect the reading. Over time, the air dissolves back into the water and will naturally disappear, as it is absorbed into the water.

How can I get 22mm take off connections on your Topway manifolds?
They are not designed for this, taking pipe only up to 20mm. However, if you wish, you can remove our take off connectors, taking care to not exert too much pressure and damaging the manifold in the process. They are factory glued in, but can be removed with care. Replace them with 1/” MBSP x 22mm copper compression connectors manufactured to BSEN 1254-2.  We recommend contacting Muller Primaflow (www.muellerprimaflow.com), product code 22009005 brass.

How do I clean and flush out an underfloor heating system?
Both new and replacement systems (a system where a new boiler is fitted is classed as a replacement system) are required by the Building Regulations1 to be thoroughly cleaned and flushed and a water treatment inhibitor added to protect the system from further corrosion. This is also particularly important where an underfloor heating (UFH) system is added to an existing heating system, to prevent the new UFH system becoming contaminated by water in the older system which may be contaminated with corrosion sediment. For further details of how to do this consult the following guides and code of practice:  
  1. Domestic Building Services Compliance Guide
  2. BS 7593 – Code of practice for treatment of water in domestic hot water central heating systems
  3. BSRIA Guide BG29/2012 - Pre-Commission Cleaning of Pipework Systems
  4. BSRIA Guide BG 4/2011 – Underfloor Heating and Cooling


Can you connect a copper pipe to any of Emmeti Manifolds?
Yes but we only cater for 10mm and 15mm pipe

Why is the amount of water in the flow meter different on different occasions?
The initial amount of air can vary depending on your fill flow rate. Then it will be affected by your pump pressure, the higher the pressure, the less air that will be visible (as air is compressed under pressure). Over time, the air dissolves back into the water and will naturally disappear, as it is absorbed into the water.

Does flow affect the amount of water in the flow meter?
The initial amount of air can vary depending on your fill flow rate. Then it will be affected by your pump pressure, the higher the pressure, the less air that will be visible (as air is compressed under pressure). Typically, you can evidence this, between when the pump is running, and when the pump is off.  Over time, the air dissolves back into the water and will naturally disappear, as it is absorbed into the water.
