Codeigniter contact form email

I'm trying to set up a contact form in Codeigniter (I'm running on xampp using Apache and I have a virtual host set up). I have the actual form working but when I try to link it up so that it emails the results I get an error. I've looked around and tried a few different solutions but I can't figure out what it is that I'm doing wrong.

Controller:

public function contact()
    {
            $this->load->helper('form');
            $this->load->library('form_validation');

            $this->form_validation->set_rules('name', 'your name', 'required', array('required'=>"<p class='required'>Please provide %s</p><br>"));
            $this->form_validation->set_rules('email', 'your email address', 'required', array('required'=>"<p class='required'>Please provide %s</p><br>"));


            if($this->form_validation->run() == FALSE)
            {
                $this->load->view('templates/headder');
                $this->load->view('contact');
                $this->load->view('templates/footer');
            }
            else
            {
                $config = array(
                    'protocol' => 'smtp',
                    'smtp_host' => 'smtp.mydomain.co.uk',
                    'smtp_port' => 465,
                    'smtp_user' => 'example@mydomain.co.uk',
                    'smtp_pass' => 'mypassword',
                    'charset' => 'iso-8859-1',
                    'wordwrap' => TRUE,
                );

                $message = 'This is a test message... do I work?';

                $this->load->library('email');
                $this->email->initialize($config);
                $this->email->from('ecample@example.co.uk', 'Tester');
                $this->email->to('example@mydomain.co.uk');
                $this->email->subject('New Query');
                $this->email->message($message);
                $this->email->send();

                if($this->email->send()){
                $this->load->view('templates/headder');
                $this->load->view('sent');
                $this->load->view('templates/footer');
                }
                else
                {
                $this->load->view('templates/headder');
                $this->load->view('contact');
                $this->load->view('templates/footer');
                }
            }
    }

View:

 <?php echo form_open('home/contact'); ?>
                <h3><span class='required'>*</span>Name:</h3>
                    <label><input type='text' name='name' value="<?php echo set_value('name'); ?>" maxlength="50" ></label>
                    <?php echo form_error('name'); ?>
                <h3>Company:</h3>
                    <label><input type='text' name='company' value="<?php echo set_value('company'); ?>" maxlength="100"></label>
                <h3><span class='required'>*</span>eMail:</h3>
                    <label><input type='email' name='email' value="<?php echo set_value('email'); ?>" maxlength="100"></label>
                    <?php echo form_error('email'); ?>
                <input id='submit_button' type='submit' value='Submit'>
